Show commits to main branch since tag/release
### Proposal
Very similar to https://gitlab.com/gitlab-org/gitlab-foss/-/issues/29648 where we can manually compare two given commits, e.g. https://gitlab.com/gitlab-playground/tag-changes/compare/v1.0...03333939642d93eab05da51fcf03138b2bd0b908, it would be a great feature, if there would be a comparison straight from the detail view of a given tag, as `GitHub` is doing it:

I think this would save couple seconds every time and feels like a great UX addition.
