Code Modernization: Rename parameters that use reserved keywords in `…

…phpunit/tests/functions/wpRefererField.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 `$echo` parameter to `$display` in `Tests_Functions_wpRefererField::test_wp_referer_field_should_respect_display_arg()`.

Follow-up to [54420], [54929].
