Remove SAFE_FOR_JQUERY from DOMPurify as it has been removed

DOMPurify removed this configuration option, so I guess it has no effect and can be removed.

See docs: https://github.com/cure53/DOMPurify?tab=readme-ov-file#removed-configuration
>  SAFE_FOR_JQUERY 	2.1.0 	No replacement required.

The PR https://github.com/cure53/DOMPurify/pull/474 also links the commits, which removed it.
