Tonya Mork bff35b8cef Code Modernization: Fix parameter name mismatch with parent in WP_Customize_Custom_CSS_Setting::validate(). ...

Renames the parameter to match the parent's method signature.
Why? PHP 8 introduces the ability to pass named arguments to function/method calls. This means the child and parent method signatures (i.e. parameter names) need to match.

Adds `@since` to clearly specify why the change happened.

Reassigns the generic parameter to the original parameter.
Why? Restoring the original name keeps the context intact within the method and makes the code more readable. An inline comment explains why this reassignment is made

Follow-up to [37476], [38829], [41376].
