Chosen Accessibility issues (Reading Blank)

Add data aria for input with chosen widget for accessibility.

Add data aria for input with chosen widget for accessibility.

I noticed that the patch add the attribute "arial-label" but the right one should be aria-label. Here's the rerolled patch.

I worked a bit on the patch to have a descriptive and more compliant aria-label.

Just added aria-autocomplete attribute too.

The patch #8 is updated to apply to the latest 4.x

The patch in #10 works if there is a single chosen element, but produces duplicate IDs if there are multiple chosen elements available.

Just add aria-label for .chosen-drop elements to the patch #10.

The 5.x branch is also available where we have a Vanilla JS version of Chosen, and there are already some accessibility fixes there, but we can add more: https://github.com/noli42/chosen
https://www.drupal.org/project/chosen/releases/5.0.2 →

I think that going forward mostly the 5.x branch will be maintained,
as to me it seems problematic that we need to add extra JS for things that should really be in the library itself.

I can reproduce #11

if there are more than one, then previous chosen elements are getting the `aria-labelled-by` attribute from the last found chosen element.

Since patches are no longer tested, a merge request needs to be provided.
