Update prometheus 2.40.4 -> 2.40.5

fix hookshot role

Fixup for 7e2e2626a0

Some references were left unrenamed which caused `validate_config.yml`
to trigger.

Update grafana 9.2.6 -> 9.2.7

This role is usable on its own and it's not tied to Matrix, so
extracting it out into an independent role that we install via
ansible-galaxy makes sense.

This also fixes the confusion from the other day, where
`matrix_postgres_*` had to be renamed to `devture_postgres_*`
(unless it was about `matrix_postgres_backup_*`).
We now can safely say that ALL `matrix_postgres_*` variables need to be
renamed.

Fix Docker installation typo in FAQ

update dendrite to v0.10.8

Regression since https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2290

More details about the new key type can be found here:
https://eff-certbot.readthedocs.io/en/stable/using.html#rsa-and-ecdsa-keys

Existing RSA-based keys will continue to renew as RSA until manual
action is taken. Example from the documentation above:
> certbot renew --key-type ecdsa --cert-name example.com --force-renewal

In the future, we may add a command which does this automatically for
all domains.

This is done via devture_systemd_service_manager_services_list_auto
already.

We expect `--tags=start` to handle systemd reloading, so we don't need
to do it manually each time we install/uninstall a .service file.
