Test on PHP 8.4+

[garak]

Our CI currently supports tests only up to PHP 8.3 due to an incompatibility with phpspec.
Until a few days ago, phpspec still didn't support PHP 8.4, and the support was added recently.
However, we also need support from phpspec-data-provider-extension, so I opened an issue on madisoft/phpspec-data-provider-extension#6
As you can see in the linked issue (and in the other issue linked there), the situation is not easy.

We should consider how to proceed, also considering that PHP 8.5 will be out next month, and currently its' impossible for us to test against it either.
If the situation in phpspec evolves, we can consider keeping it and testing at least on PHP 8.4. However, the only solution in the long run seems to be ditching phpspec and migrating our test suite to PHPUnit.

A question that may be debated, but I'll take the plunge: did we think about moving from phpspec to phpunit?

We have been using phpspec at Akeneo since a long time, but we are now dropping it because the support and the community around phpspec is not as good as what we can have with phpunit.

I have a little guy named Claude with me who would be glad to suggest a PR 😉

@jmleroux that's exactly what I proposed in my last sentence (see above). A PR would be welcomed

[jmleroux]

Will do

I started an experimental PR, with Claude doing all the boring job

It is a pita to support 8.1 -> 8.4.

8.1 security support will end in December. What would you think about dropping support and start tagging Poser v4?

8.1 can be dropped in a minor version
