Timo Tijhof 93351fb7d9 Use native <input required> instead of JS-based disabled toggling ... Remove the JavaScript module and its logic to toggle the disabled state on the submit button. Instead, let the browser handle this natively by setting the `required` attribute, which naturally prevents early submissions. Retain the current styling for 99% of cases by using the :required:invalid selector to target the submit button to make it appear disabled. This slight duplication of styles is needed because, despite the form effectively being disabled natively, the core mediawiki-ui styles only account for :disabled on the button directly and not e.g. inherited via form:invalid. It is also unclear whether we would want that, since there is some value to be had from having the form give a consistent look with a progressive button that can be submitted even at the wrong time to yield an assistive message to the required field, so hence handling this locally for now instead of with a generalised approach. In order to use the required true/false idiom, I have switched the generating of the HTML string from the old Xml::element method to Html::element. This means there is no need to store it in an array first and conditionally set it since true/false will result in absence or required="" as needed. As side-effect from this, redundant attributes like value="" and type="text" are ommitted from the output, just as MediaWiki core does more generally.
