MAINTAINERS: Remove myself as reviewer

MAINTAINERS: Remove myself as reviewer

Finally taking this off my to-do list. It’s been a privilege to be part
of this project, but I am no longer actively involved in reviewing
Python code here, so I believe it's best to update the list to reflect
the current maintainers.

Please, feel free to reach out if any questions arise.
