chore: workflows call workflows (#7089)

Relying on tags to trigger workflows makes it hard to trace what's
happening after a release, currently:
1. We manually trigger a release workflow
2. The release workflow executes and tags the new release in code
3. Several other workflows trigger after matching the tag doing
different things: build docker images, tarballs and other things.

This creates a loose dependency between the workflows which are actually
part of the same "release workflow" which makes it difficult to spot
when one or other dependent workflow fails because the dependency is
indirect through the tagging mechanism.

This PR switches to a more direct approach using [workflow
calls](https://docs.github.com/en/actions/using-workflows/reusing-workflows).
This will create a graph as shown in the following graph:
![](https://docs.github.com/assets/cb-34427/mw-1440/images/help/actions/reusable-workflows-ci-cd.webp)
making it easier to track and identify any problem.

The "drawback" of this approach is that previously we could trigger all
dependent workflows at once by creating a tag matching the expected
pattern without manually triggering a new release. This limitation can
be overcome by adding a manual workflow_dispatch to the workflows using
the tag trigger.
