JavaScript coding standards

With the switch to GitLab CI, all the JavaScript coding standards are now reported from eslint.
See for example: https://git.drupalcode.org/project/votingapi_widgets/-/jobs/2410740

There is an automated patch in the pipeline output that can fix all of these. HOWEVER, we really should fix the jQuery once issues first before we start messing with code style.

Reopening because this needs to be fixed for a D11 release.

That seems to have fixed all the issues.

I would appreciate a review of the Fix 'Prefer addEventListener to $.bind jquery/no-bind' changes and the Fix 'Prefer value to $.val jquery/no-val' changes
