Mautrix-Facebook repo location update, pin v0.3.1

The Github link is just a redirect to Tulir's own GitLab, so I replaced the self-build link
The docker container repository was rearranged hierarchically (dock.mau.dev/tulir/mautrix-facebook -> dock.mau.dev/mautrix/facebook)
Tagged versions have been made available, thus :latest -> :v0.3.1

Update howto-server-delegation.md

The default of using the `matrix` database is better anyway.

The attached code for the "Serving the Federation API with your certificates and matrix-nginx-proxy" section suggests using the matrix.<your-domain> certificate for the federation API as opposed to the necessary <your-domain> certificate for the federation to work. This can cause some confusion to readers.

Updating to ma1sd v2.5.0

Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1171

GoMatrixHosting v0.5.5

Update configuring-well-known.md

Added selfbuild functionality to matrix-reminder-bot

All of `setup_install.yml` only runs if `matrix_bot_matrix_reminder_bot_enabled`,
so it's not necessary to add that condition once again.
