Fix T53406: Avoid toggling visibility on Collision modifier

Bumped version to 0.2.5
Since the Collision modifier visibility was not exposed in the UI
trying to avoid unreliable results related to physics
and possibly broken setups, for now skip it in the add-on

Add reports about skipping:
- Skipped modifier name is appended
- If there are only skipped modifiers, add a new message about it

Correct bl_name of some operators so they are easier to search
