I have tested this item ✅ successfully on d71883c

@alikon @mahmoudmagdy1-1 @laoneo ✅ Successfully tested fpr 5.4-dev with branch from PR on own fork:

• Created Codespace
• Logged in to Joomla administrator backend, enabled 'Debug System' and 'Log Almost Everything', played arround and checked the Joomla log files with 4LOGS plugin and in VSC
• Installed German language packet as extension by file upload and configured as Administrator default
• Installed module zitat-service.de from JED, configured and checked it is working
• Running some Cypress tests with GUI manually
• Running full System Tests headless (takes 24 minutes –  I think that leaving Xdebug enabled all the time reduces performance and is therefore not recommended from my point of view, also 33 of 148 failed - but the env is for sure not recommended to run all the System Tests)
• Logged in to phpMyAdmin
• ❌ Failed to install Patchtester 4.4.0 with file upload
  • Solved by installing via URL, fetching data works, applying a PR works and file is changed
• ❌ Tried to register for automated updates: Error while registering to automated update service: Invalid JSON body (500).
• Direct testing a PR as documented is only possible after merge and GitHub action is available for 5.4-dev branch
• Installed vim package 😄, forced PHP error and checked it is logged in /var/log/php_errors.log file
• ⚠️ Compared the 5 new files with [6.0] Add Support for Github Codespaces #45719 already merged 6.0-dev branch there are a lot of differences, I would recommend to unify for 5.4 and 6.0 or at least have only the difference in PHP 8.2 and 8.3
  • See diff.txt

Restrictions and workarounds, as well as the Codespace usage paying needs to be documented. I will do.
