[CI] Generate full baseline upon PHPStan failure

After some headache, now found the right regex to have sed adjust the paths of the generated baseline so it can be really just copy/pasted to the branch with no additional edit.

I actually ran into this issue earlier today by chance (the paths not being correct).

This looks good and will make some things easier, but also allow for a good interface in gitlab for changes as per 📌 [CI] Report PHPStan baseline statistics in job Active .

All good, working as intended :)
