We're starting it with `--user` and dropped capabilities, after all.

Hopefully fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/2188

update remote-repo-infos with link to doc

update link to example

in my environment i see the matrix. conf in that file: /matrix/nginx-proxy/conf.d/matrix-domain.conf

was a litte confusing for me, so i added the link to the syntax-descr.

We haven't encountered such a problem yet, but it doesn't hurt to
make things more robust.

These values that we were setting also make sense in the context of the
`matrix-postgres` role even when not used within the playbook.

grammar correction

the word "both" would refer to only 2 urls in this context

Just specifying `15` means we won't automatically re-pull `15.1` when it comes out.

We're overriding these in the correct way in `group_vars/matrix_servers`
so this wasn't causing any problem in practice.
