Extend cherry-pick tracking to command line cherry-picks

Problem to solve

With !22209 (merged) we developed #36130 (closed) to track MR deployments when the commit is cherry-picked.

This feature only works if the cherry-pick is performed with GitLab (either API or web interface).

This issue is to track the proposal to extend it to git cherry-pick -m 1 SHA performed on the user workstation.

Intended users

• Rachel (Release Manager)
• Parker (Product Manager)
• Sasha (Software Developer)

Further details

In #36130 (closed) this was discussed, but we decided to avoid parsing commint messages to detect cherry-picks.

Over time we'll gather more date about our-own usage of the feature and we could use that information as a test-set for this feature
