[Feature] Add the possibility to remove a media from a collection. #1557

What problem does this solve?

In 1.5.1 it's possible to add a media to a collection but not to remove one from it. It would be nice to have the possibility, so that user-managed collections can work normally.
Actually when in a collection, the right click on a media doesn't do anything on pc, but a long press shows the menu on mobile, just the menu have an option to add to another collection but not remove it.

Proposed solution

It would be great to have, with the right click or a long press on mobile/tv, an option "remove from collection" from the menu.

Platform

All / Not platform-specific

Alternatives considered

Within Moonfin, I don't see any other solution.
