Code Modernization: Rename parameters that use reserved keywords in phpunit/tests/media.php.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit renames the `$match` parameter to `$matches` in shortcode image tests.

Note: This is enforced by WPCS 3.0.0.

Follow-up to [56693].

See #58831.
