`matrix_nginx_proxy_enabled` is usually set to false by users, this is when
the warning should be displayed.

Fixup for d8a19e5bf9

Building mx-puppet-discord appears to have been broken for a while.

We'd rather use a fork that is maintained better and by someone who
cares about whether their software works or not, so we'll be using the
Beeper-maintained for from now on.

In the future, we should probably do the same for the Slack bridge
which is also part of the same monorepo
(https://gitlab.com/beeper/mx-puppet-monorepo).

Various roles depend on this. It makes sense to make it part
of the `matrix-base` role.

Previously, when matrix-postgres was disabled, we were setting
`matrix_mautrix_twitter_database_engine` to an invalid empty value.

Now, we always hardcode `matrix_mautrix_twitter_database_engine: postgres`,
but set/unset the database hostname and password values instead.

This allows disabling the automatic portal bridging, meaning bridges
must be manually setup via self-servicing, by setting:

    matrix_appservice_discord_bridge_enableSelfServiceBridging: true
