We should document which GitLab Group has ownership of which Managed App

Problem

The number of integrated CI/CD GitLab Managed Apps is growing each day.

Different teams, internal and external, have been adding those applications. Therefore, the domain expertise is not consolidated in a single team, thus it might be difficult to find out who is the best team to reach out to when support is needed.

Proposal

We should have a clear documentation on which team is responsible for each GitLab Managed App.

We have already done something like this for PostHog:

We could do the same for other apps but, in case of GitLab support, we could phrase something like this:

Note: Support for the {Application Name} managed application is provided by the {GitLab Group} GitLab group. If you ran into issues, open an issue on GitLab and label the issue with {Group Label}.
