Summary of Changes

Extends the PHPStan task for Github workflow that it updates the PHPStan baseline file when PHPStan was running successfully. If PHPStan fails then the baseline file will NOT be updated and the action aborts. I'v also made a change where I replaced some deprecated code, to illustrate how the functionality works. The commit is added by the bot in d1fc727.

Testing Instructions 1

• Copy the /.github/workflows/ci.yml file to the branch
• Add the code Joomla\CMS\Factory::getDbo(); to the file /libraries/src/Date/Date.php after line 85
• Commit the changes to the branch and push to the fork
• Check the Action
