Fix XDebug Support for new Wodby Images
Wodby changed their PHP image with regard to XDebug:
- https://github.com/wodby/php/commit/c9496a6ed2cd23717b96757851e99cb1708166ae
- https://github.com/wodby/php/commit/f765f6e893e335cfdf852704406adb7e2e4a47b3
We now have to set PHP_EXTENSIONS_DISABLE: 'xhprof' when debugging is on, and remove that line otherwise.
