HTML API: Use more universal syntax to call Closure variable.

Replace `( $fn )( ...$args )` syntax with equivalent `call_user_func( $fn, ...$args )` to prevent an issue with the WordPress documentation parser. The parser would fail when encountering this syntax, preventing documentation generation.

Developed in https://github.com/WordPress/wordpress-develop/pull/10907.

Follow-up to [58304].
