Fixup for https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1899

Co-authored-by: Slavi Pantaleev <slavi@devture.com>

This shall indicate that the public url of maubot is here configured the same as matrix_server_fqn_matrix but this must not be the case.
In the config I used the matrix fqnd directly as this part of the config is directly bound to the homeserver we want to connect to (but can not use the internal)

The /data is hardcoded in the container

Fixup for ba51997f7b

We redefine these variables in `group_vars/matrix_servers`, but it's better
to have some defaults in the role as well.
