Extend the release script to wait for GitHub Actions to finish and to be usable as a guide for the whole process. (#13483)

Summarized from @richvdh's reply at https://github.com/matrix-org/synapse/pull/13589#discussion_r961116999

It was really easy to miss the `enable_metrics: True` step with the previous language.

Otherwise they'll be leaked due to the filtering code only respecting
the stable identifiers for private read receipts.

This avoids doing work that will never be used (since the
resulting unread counts will never be sent in a /sync
response).

The negative of doing this is that unread counts will be
incorrect when the feature is initially enabled.

* Add missing graph to contrib

* Update with minor but plausible changes, including positioning changes

Fixes #13206

Borrows some text from https://github.com/matrix-org/synapse/pull/13647
for the changelog.

The method doesn't actually do any data fetching and the method that
does, `_get_joined_profile_from_event_id`, has its own cache.

Signed off by Nick @ Beeper (@Fizzadar).

Generalise the `@cancellable` annotation so it can be used on functions other than just servlet methods. (#13662)

The --force flag of dpkg-statoverride has been deprecated (apparently starting
with the dpkg version in Debian buster). It offers --force-all as q quick fix,
but the usage in the Debian postinst script is probably covered by
--force-statoverride-add.

Fixes: #8391
