We no longer ask users to create Matrix user accounts for these bots:
- Postmoogle
- Honoroit
- Reminder Bot
Other bots and services (matrix-registration-bot, maubot, mjolnir,
Dimension, etc.) require an Access Token to run (not a password),
so this new role doesn't help for them.
It does help for the above bots though, and for defining your own
"initial user accounts" in the `matrix_user_creator_users_additional`
variable.
