Subgroup database tables are not removed after un-install

Problem/Motivation

After un-installing the Subgroup module, the database tables related to Subgroup are not removed from database. I'm using Drupal 11.1.5, Subgroup 3.1.0, and Postgres 16.6.

Steps to reproduce

1. Ensure you are using Postgres 16 as the back end database
2. Install Subgroup 3.1.0
3. Execute composer require drupal/subgroup
4. Within Drupal, go to Manage --> Extend and install Subgroup. Note that new tables are created in database: group__subgroup_depth, group__subgroup_left, group__subgroup_right, group__subgroup_tree.
5. Now go back to Manage --> Extend and un-install Subgroup module.
6. Observe that all 4 Subgroup related tables remain in the database.
