PR Summary

• Introduction of a New Backwards Compatibility Check Workflow
  A new Github Actions workflow, intended to ensure backwards compatibility, has been added. This routine gets activated when updates are made to the project's repository. It primarily focuses on checking for changes in specific files like the source files, workflow definition, and project dependencies configuration. It uses an existing, pre-defined workflow provided by yiisoft/actions to run the checks in an Ubuntu environment with the PHP version of 8.1.

• Removal of the Previous Compatibility Check Workflow
  The previous Github Actions workflow, which also performed similar checks but using an action defined by nyholm/roave-bc-check-ga, has been discarded. This change streamlines the checking process by using only one workflow with a standard set of rules.
