Update to jQuery UI 1.14.0

The current 1.14.0 milestone: https://github.com/jquery/jquery-ui/milestone/4

The jQuery UI roadmap hasn't been updated in over seven years: https://jqueryui.pbworks.com/w/page/12138038/Roadmap

Currently, we are on beta2, which is the latest. Marking postponed until the next milestone comes out.

I added a comment to 📌 Update to jquery UI 1.14.0 beta Downport tentatively signing off on backporting this to 1.14 as well. (I commented there because there are some changes to the core vendor tooling script that look like they might've needed to be done by hand, but we could also mark that issue to fixed and open a 10.4 MR with the full update on this issue.)

Might be easier to add the diff from that MR to a 10.4 backport here, let's keep both issues open until we've got the 11.x commit done.

Test failure on the MR is real but looks like it probably just needs the expectation to be updated?

Looks great.

Committed dea61b8 and pushed to 11.x. Thanks!

10.4.x MR is up

Can't rerun it as not a committer but see unit tests failed to run

Actually see the failure on a few MRs so believe unrelated.

Committed/pushed to 10.4.x, thanks!
