Edit installing instructions (#3844)
* Replace "just run-tags install-all/setup-all,start" with "just install-all/setup-all"

Thanks to the tip by Slavi that the overhead of ensure-matrix-users-created is negligible.

* Edit installing instructions

- Move the anchor links to docs/just.md
- Add note about running "ensure-matrix-users-created" tags, if ansible-playbook's tags not "setup-all,ensure-matrix-users-created,start", ie. either "setup-all,start", "setup-email2matrix,start", "setup-aux-files,setup-corporal,start", or "setup-matrix-user-verification-service,start"

* Update descriptions about installation

- Introduce the most conservative and stable raw ansible-playbook command.
- Introduce the just commands on installing.md and maintenance-upgrading-services.md, not on quick-start.md, since it is too early for quick start guide readers who are just starting to climb learning curve to use the shortcuts.

* Update docs/configuring-playbook-etherpad.md: remove the note about ensure-matrix-users-created

# Setting up Mautrix Telegram bridging (optional)
The playbook can install and configure [mautrix-telegram](https://github.com/mautrix/telegram) for you.
See the project's [documentation](https://docs.mau.fi/bridges/python/telegram/index.html) to learn what it does and why it might be useful to you.
## Prerequisite (optional)
If you want to set up [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do) for this bridge automatically, you need to have enabled [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) or [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service for this playbook.
For details about configuring Double Puppeting for this bridge, see the section below: [Set up Double Puppeting](#-set-up-double-puppeting)
## Adjusting the playbook configuration
You'll need to obtain API keys from [https://my.telegram.org/apps](https://my.telegram.org/apps) and then add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
```yaml
matrix_mautrix_telegram_enabled: true
matrix_mautrix_telegram_api_id: YOUR_TELEGRAM_APP_ID
matrix_mautrix_telegram_api_hash: YOUR_TELEGRAM_API_HASH
```
## Installing
After configuring the playbook, run it with [playbook tags](playbook-tags.md) as below:
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
```sh
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,ensure-matrix-users-created,start
```
**Notes**:
- The `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account.
- The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
`just install-all` is useful for maintaining your setup quickly when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed.
## Usage
You then need to start a chat with `@telegrambot:example.com` (where `example.com` is your base domain, not the `matrix.` domain).
If you want to use the relay-bot feature ([relay bot documentation](https://docs.mau.fi/bridges/python/telegram/relay-bot.html)), which allows anonymous user to chat with telegram users, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
```yaml
matrix_mautrix_telegram_bot_token: YOUR_TELEGRAM_BOT_TOKEN
matrix_mautrix_telegram_configuration_extension_yaml: |
bridge:
permissions:
'*': relaybot
```
You might also want to give permissions to administrate the bot:
```yaml
matrix_mautrix_telegram_configuration_extension_yaml: |
bridge:
permissions:
'@user:example.com': admin
```
More details about permissions in this example: https://github.com/mautrix/telegram/blob/master/mautrix_telegram/example-config.yaml#L410
If you like to exclude all groups from syncing and use the Telgeram-Bridge only for direct chats, you can add the following additional playbook configuration:
```yaml
matrix_mautrix_telegram_filter_mode: whitelist
```
### 💡 Set up Double Puppeting
After successfully enabling bridging, you may wish to set up [Double Puppeting](https://docs.mau.fi/bridges/general/double-puppeting.html) (hint: you most likely do).
To set it up, you have 2 ways of going about it.
#### Method 1: automatically, by enabling Appservice Double Puppet or Shared Secret Auth
The bridge automatically performs Double Puppeting if [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) or [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service is configured and enabled on the server for this playbook.
Enabling [Appservice Double Puppet](configuring-playbook-appservice-double-puppet.md) is the recommended way of setting up Double Puppeting, as it's easier to accomplish, works for all your users automatically, and has less of a chance of breaking in the future.
Enabling double puppeting by enabling the [Shared Secret Auth](configuring-playbook-shared-secret-auth.md) service works at the time of writing, but is deprecated and will stop working in the future.
#### Method 2: manually, by asking each user to provide a working access token
**Note**: This method for enabling Double Puppeting can be configured only after you've already set up bridging.
When using this method, **each user** that wishes to enable Double Puppeting needs to follow the following steps:
- retrieve a Matrix access token for yourself. Refer to the documentation on [how to do that](obtaining-access-tokens.md).
- send `login-matrix` to the bot and follow instructions about how to send the access token to it
- make sure you don't log out the `Mautrix-Telegram` device some time in the future, as that would break the Double Puppeting feature
