Allow custom data-options to added to elements JavaScript options

Resolved merge conflict. Problem was that we're hacking on the file modules/webform_toggles/js/webform_toggles.element.js that's no longer there due to 📌 Deprecate the use of drgullin/icheck Active . I simply removed the file. If folks are interested in making this change in Webform Deprecated → , they can dig it out of the commit.

Here's a Composer-friendly patch for 6.2.x, which assumes that #3452986-18: Update jquery.intl-tel-input to v23.0.10 and add option for i18n → has already been applied.

People should weigh-in if this enhancement is useful.

I think the concept is useful, but sometimes the customization can't be hard-coded as data attributes, but rather rely on runtime information.

One example is for the international telephone element. See https://git.drupalcode.org/project/webform_intl_tel_national_mode/-/blob... for a somewhat heavy handed fix for how most UX problems were resolved.

Were there a client side event to tap into, it'd make things a lot easier to tweak. I would LOVE to take a holistic pass on the telephone input given how many quirks there are, and if there was more robust options handling, that'd be even easier.
