Gitlab CI changes for ignored deprecations

This works now, Thanks to @fjgarlin.

Reviewing this

Looks good to me.
I reviewed the MR and the ignore path was updated. The hardcoded path was changed in ignore path for SYMFONY_DEPRECATIONS_HELPER.
The PHPUnit test that were earlier failing have now been resolved and the PHPUnit pipeline is now green.
Moving it to RTBC+
Can be merged

Thanks a lot for finding and fixing this!
