[2.0.x] Group Mapping From Node

I am requesting permission to opt the Group Mapping From Node project into Drupal.org security advisory coverage.

Project:
https://www.drupal.org/project/group_mapping_from_node

Branch for review:
2.0.x

Recent release/tag:
2.0.0

Summary:
This project provides a simple node form integration that allows a node to be mapped to a Group relationship. I recently updated the module for Drupal 10.3 and Drupal 11 compatibility and updated the code to use the newer Group relationship API.

I understand that opting into security advisory coverage means I agree to follow Drupal secure coding practices, respond to security reports responsibly, and cooperate with the Drupal Security Team when needed.

Current status:
- The Drupal 11 compatibility code has been committed.
- The 2.0.x branch has been pushed.
- The 2.0.0 tag has been pushed.
- composer.json has been added.
- The module info file uses core_version_requirement.
- PHP syntax check passed.

Please review this project for permission to opt into security advisory coverage.
