Make the tutorial's docker-compose versioned

[colega]

Is your feature request related to a problem? Please describe.

The play with Grafana Mimir tutorial is published from a specific version, however it points to the main branch in the repo.

On the other hand, the main branch in the repo points to the latest tag in the docker hub, which is the latest specific release version.

This prevents us from adding new features to the tutorial until the release is published.

Describe the solution you'd like

The tutorial in main should use the image that commit builds (i.e., we should publish the main tag). The tutorial in the release branch, should point to the published release version instead.

The published tutorial should point to the latest release tag in the repo by specifying it in the cloning instruction, like:

git clone --branch mimir-2.2 https://github.com/grafana/mimir.git

Describe alternatives you've considered

Let it be this way.
