CI: Install PHPUnit 7.5 for WP < 5.9

See https://make.wordpress.org/core/2021/09/27/changes-to-the-wordpress-core-php-test-suite/#integration-tests-ci-changes - PHPUnit 9 removed a `PHPUnit\Util\Getopt` class, but the [fix](https://core.trac.wordpress.org/changeset/51570/) wasn't applied to WP until 5.9. Also - exclude WP 5.7 on PHP 8.2 since it is not supported.
