We do this to match Synapse's new default "max_upload_size" (50MB).
This `matrix_nginx_proxy_proxy_matrix_client_api_client_max_body_size_mb`
default value only affects standalone usage of the `matrix-nginx-proxy`
role. When the role is used in the context of the playbook,
the value is dynamically assigned from `group_vars/matrix_servers`.
Somewhat related to #692 (Github Issue).
The regex introduced in 63a49bb2dc seems to take precedence
over the bare location blocks, causing a regression.
> It is important to understand that, by default, Nginx will serve regular expression matches in preference to prefix matches.
> However, it evaluates prefix locations first, allowing for the administer to override this tendency by specifying locations using the = and ^~ modifiers.

While v1.22.0 supposedly has multi-arch Docker images
(thanks to https://github.com/matrix-org/synapse/pull/7921),
I can't them on Docker Hub yet, so I'm backing out of this change
for now and letting people fall back to self-building there.
If the SQLite database was from an older version of Synapse, it appears
that Synapse would try to run migrations on it first, before importing.
This was failing, because the file wasn't writable.
Hopefully, this fixes the problem.
Interestingly, no one has reported this failure before #662 (Github
Issue).
It doesn't make sense to keep saying that we support such old Ansible
versions, when we're not even testing on anything close to those.
Time is also passing and such versions are getting more and more
ancient. It's time we bumped our requirements to something that is more
likely to work.
