[PHP] - phpunit upgrade

[FabioBatSilva]

Hi.

This is meant to reduce the noise when running php tests and make the test a bit more friendly.

There is a ton of warnings happening currently due to deprecation on phpunit..

What is included :

• Upgrade to phpunit 10.5 * Add generated files to git ignore
• Add phpunit.xml and bootstrap
• Remove Polyfill for phpunit6

I have a few other PRs coming for issues I have open. And this should make the contributing a bit easier for me other future contributors..

Test failures look like this needs a rebase and retest.

Hi,

Would be nice to have this merged and add CI runs for PHP 8.4 and 8.5.

There are still PHPUnit deprecations (phpunit --display-phpunit-deprecations):

14 tests triggered 14 PHPUnit deprecations:
