[4.x]: Revoking permissions from user group via project config does not work if all permissions in group is revoked

What happened?

Description

When removing permissions from a user group, and pushing project config changes to a different environment, it's not possible to completely remove all permissions in a group of permissions (for instance "Users"). If one or more permissions is set, they are updated correctly.

Steps to reproduce

1. Create a user group with some Users permissions set.
   

2. Push updated project config to an environment that applies these changes.

3. Change permissions by completely removing all permissions within a permissions group.
   

4. Push updated project config to an environment that applies these changes.

Expected behavior

The user group should have no permissions to Users.

Actual behavior

The user group have the permissions previously set.

If I keep at least one permission checked in the permissions group, everything works as expected.

Start by reproducing the project-config deployment described for Craft CMS 4.3.10, comparing a permissions group with one selected permission against a group with none. Trace the user-group permission update path and verify that the deployed configuration removes previously granted Users permissions; done means the target group has no Users permissions after the second push.
