Adding the defaults in addition to template, switching YOUR_DOMAIN to {{ matrix_domain }}, and giving example of the two combined, as the playbook gives a warning about things being defined twice, so only using the last one in the vars.yml

Fixing code block formatting

Copy/Pasting from docs/configuring-playbook-bridge-mautrix-facebook.md but with the relevant variable names changed to add turning on encryption and a puppet admin.

Adding a bit on how to bind the synapse ports if the webserver isn't in the same docker network, or on a different machine.

Logging in from the IP address is no longer always enough, but 2FA seems to work eventually

Fixup for #1877.

Based on mautrix-whatsapp, as that's what the bridge software is based on.

This is a poor way to do things though. It may break again in the future.
matrix-registration is a poorly maintained project and should likely be removed from the playbook.

The old link returned a 404 so I thought I throw in joinmatrix.org :)

* Add matrix-registration-bot

This adds an install and uninstall task plus helpers. The bot is disabled by default.
This commit does not include documentation, yet. In short, the bot can be enabled by adding
matrix_bot_matrix_registration_bot_enabled: true
matrix_bot_matrix_registration_bot_matrix_user_password: "verysecret"
matrix_bot_matrix_registration_bot_matrix_admin_token: "supersecret"
to the host_vars

* Change bot username to bot.matrix-registration-bot following convention

* Address smaller remarks, fix local docker build

* Switch to an env file

* Add environment variables extension for additional config

* Add documentation for the matrix-registration-bot

* Add screenshot on how to obtain admin access token

* Use bot as admin to only have one access token (bot and admin api)

* Use cleaner setting of matrix_synapse_registration_requires_token

* Use config file for cleaner more secure usage

* Delete unneeded env

* Rename vars to make usage clear

* Fix typos/wording and add notice about logging out

* Convert configuration to use |to_json

* Reorder role includes

Nothing should be after `matrix-common-after`.

`matrix-bot-matrix-registration-bot` can probably be anywhere, but it makes sense to put it next to the other `matrix-bot-*` roles.

* Minor group_vars/matrix_servers touchups
