GH Actions/test: fix coverage cache warming

The PHPUnit coverage cache warming step was not being run for PHPUnit 10 or 11, while it should be to prevent issues with PHP Parser, like this:
```
Message:  Token T_PUBLIC_SET has ID of type string, should be int. You may be using a library with broken token emulation
Location: /home/runner/work/PHP_CodeSniffer/PHP_CodeSniffer/vendor/nikic/php-parser/lib/PhpParser/compatibility_tokens.php:35
```

This commit should fix this.
