Please add support to PHP 8.4

Thanks for the reminder.

I'm keeping this issue open & pinned because there are still some problems with xdebug and pcov:

• xdebug stable does not yet support PHP 8.4 (using beta version in our image, I'm monitoring their releases) xdebug 3.4.0 stable is out
• pcov has an error because of a PHP internal function changing signature (monitoring the PR); this version cannot be installed from source because the branch is missing the package.xml file (it is available only in their release branch) and I really didn't want to write a convoluted workaround to clone the correct files in a local directory and install it from there, so I disabled the build of our pcov image for PHP 8.4

The images arrived at Docker Hub and work as expected! 👏 🙏

Both xdebug and pcov have been updated, new images are building now
