ComponentPluginManager must implement CategorizingPluginManagerInterface

I will try to propose a MR.

Looking forward to an MR to review! 🤓

If you wish, you can have a look on an existing and well tested implementation of this interface for SDC plugin manager: https://git.drupalcode.org/project/ui_patterns/-/blob/2.0.x/src/Componen...

Implemented the changes required in the MR. Please review.
