Type error in Setting Form.php

Patch for the fix.

Thanks!
The patch above fixes the problem.

@arjak-mondal What version of Drupal are you using?

@arjak-mondal @rolki

The provided patch is not okay. It fixes the issue on D11 but breaks D10.

Please test MR on D10 and D11, and if it all works fine, I will merge it.

Hi
have manually tested MR 18 on Drupal 10 and 11 version.
The MR is applied Successfully...

The themed_fast_404 page is working as expected. The page is not broken and also not throwing any error.
