Fix T76014: correct description of COLLECTION_OT_objects_remove_all

before rB17bd5c9d4b1e it was "Remove selected objects from all groups"

- `BKE_object_groups_clear` is not checking if a collection is linked
to the current scene...
- rB713010bd7795 did not change that either

So this indeed removes selection from _all_ collections, so account for
that in the operator description/idname.
