feat: #3595161 Automated Drupal 12 compatibility fixes
Applies the Project Update Bot rector patch from 2026-07-11 unchanged, apart from the info.yml files, where the packaging script lines cannot be applied to git. Converts the procedural hooks to object oriented hook classes, replaces REQUIREMENT_ERROR with RequirementSeverity through DeprecationHelper, raises core_version_requirement to ^10.1 || ^11 || ^12 and adds the Group attribute to the test classes.
Closes #3595161
