PR Summary

• Update to MySQL Docker Base Image Version
  The blueprint that we use to build our MySQL docker container (Dockerfile) has been modified. Previously, we were using an older version (8.1) of MySQL's official Docker image as the foundation for our own. With this change, we're now using a more recent version (8.4).
  This adjustment means our systems will benefit from the latest features and improvements made available by the MySQL team, such as better performance, security enhancements, and any identified bug fixes.
