Coordination: Prepare for students code using PHP 8.3

[mk-mxp]

For exercism/php#652 we need to have the representer ready to accept PHP 8.3 code from students. The representer itself may run on a different PHP version.

@homersimpsons Can you outline the required work to do here? An actionable list of tasks would be perfect, but any hints are welcome.

To me there is nothing to do:

• https://github.com/nikic/PHP-Parser already supports PHP 8.3
• https://www.php.net/releases/8.3/en.php there does not seem to be anything important to normalize, things that may be great to normalize are:
  • Remove the #[\Override] attribute
  • Remove the type for class constant

That said I could also update the base docker image of the representer so everything runs on PHP8.3

I will mark the presenter as ready for PHP8.3, as your additions most likely won't affect any solutions soon.

For running on PHP 8.3: Use XDEBUG_MODE=off for performance reasons. I found at many places, that there is a huge impact even for small programs against having the default mode.

For the record, I did upgrade the runtime for the representer to PHP8.3.

I did not try to change XDEBUG settings nor looked into the 2 normalizations I did suggest above. So I will let this issue open for now.
