PHPUnit 12 support

This release updates the PHPUnit Polyfills to allow for "writing your tests for PHPUnit 12 and running them all the way back to PHPUnit 7". [*]

Please keep in mind that the PHPUnit Polyfills provide forward-compatibility. This means that features which PHPUnit no longer supports in PHPUnit 12.x, are also no longer supported in the 4.0 release of the PHPUnit Polyfills.

Please refer to the PHPUnit 12 release notification and PHPUnit 12 changelog to inform your decision on whether or not to upgrade (yet).

Projects which don't use any of the new or removed functionality in their test suite, can, of course, use the PHPUnit Polyfills 1.x, 2.x, 3.x and 4.x series side-by-side, like so composer require --dev yoast/phpunit-polyfills:"^1.0 || ^2.0 || ^3.0 || ^4.0".

[*]: Note: Releases from the PHPUnit Polyfills 4.x branch will support running tests on PHPUnit 7.5.0 - 9.x, 11.x and 12.x, but will not allow for running tests on PHPUnit 10 (for reasons explained in [#​200]). In practical terms, the net effect of this is that tests on PHP 8.1 will run on PHPUnit 9 instead of PHPUnit 10. Other than that, there is no impact.
