Adding a Tag to a Prefab does not apply to pre-scene instantiated Prefabs

[Pieeer1]

Describe the bug

When adding a prefab to a scene with no tags, it gets added perfectly fine. Going to modify the prefab and adding a tag to the prefab menu, and saving it, does not propagate to the prefabs already added to the scene.

To Reproduce

1. Create a new Prefab and Save it
2. Add a Prefab Reference to the scene
3. Add a Tag to the Prefab
4. Go check the Prefab reference in the scene, it will have no tag

Expected behavior

The tag should propagate to all existing prefabs... like other prefab changes

Adding tags to prefabs works fine for me, but removing tags is broken. Prefab instances will keep the old tag even when it has been removed from the actual Prefab.

This is fixed.

Can no longer repro adding tags not updating nor removing tags not updating.
