Slavi Pantaleev d82d0ad84b Add _metrics_proxying_enabled variables to mautrix bridges
Related to https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2427

`metrics_enabled` should only expose the metrics locally, on the
container network, so that a local Prometheus can consume them.

Exposing them publicly should be done via a separate toggle (`metrics_proxying_enabled`).
This is how all other roles work, so this makes these mautrix roles consistent with the rest.

msg: >-
Trying to append mautrix-whatapp-metrics's reverse-proxying configuration to matrix-nginx-proxy,
but it's pointless since the matrix-nginx-proxy role had already executed.
To fix this, please change the order of roles in your playbook,
so that the matrix-nginx-proxy role would run after the matrix-bridge-mautrix-whatsapp role.
