Allow PHPUnit 12

[Jean85]

This is a tentative PR to see if we can just widen the constraint or if we need more work.

the CI has not installed PHPUnit 12. Maybe there is another conflict somewhere

Would think in prophecy sebastian package requirements: https://github.com/phpspec/prophecy/blob/a0165c648cab6a80311c74ffc708a07bb53ecc93/composer.json#L23-L25

But that in turn has another conflict, which stops even PHPUnit 11 along the Prophecy chain: phpspec/phpspec#1483

If we can merget that, we can progress toward PHPUnit 12 too.

looks like this can be updated as https://github.com/phpspec/phpspec/releases/tag/7.6.0 was released?

[Jean85]

Yes, also with phpspec/prophecy#643 I've tested that Prophecy runs smoothly with PHPUnit 11-12.

I'll try to rebase/force push to trigger another CI run.
