feat: allow PHPUnit 11

#226

[Jean85]

PHPUnit 11 does not support PHP 8.1, but you still have failure there too: https://github.com/facile-it/paraunit/actions/runs/7754078301/job/21146669794?pr=225#step:6:11

I suspect the build is broken on the main branch too.

Thanks for working on this
#227

[Jean85]

Wow, incredible! After making the base build green with #227, it works flawlessly without any change!

I'll add a changelog entry and release it!

[Chris53897]

perfect, thanks

it works flawlessly without any change!

@Jean85 that's because PHPUnit was not allowed after all.

PHPUnit 11 requires phpunit/php-code-coverage:^11.0: https://github.com/sebastianbergmann/phpunit/blob/11.0.0/composer.json#L35

Which is not allowed:
https://github.com/facile-it/paraunit/blob/2.3.0/composer.json#L30

[Jean85]

Aw crap, my fault! I didn't check that 11 was effectively running...

I'm on it: #228

[Jean85]

Watch out, there's #229 too, and I've already posted a comment there.
