Update jQuery v3.6.4 to v3.7.0

[mgol]

Hey! The jQuery team is preparing for a release of jQuery 3.7.0. While formally not a breaking update, there are major changes in that version that incur some risk. Before we release, I'm trying to verify the changes are not breaking important projects.

What we'll release as 3.7.0 should be very similar to what you can currently find at ​https://releases.jquery.com/git/jquery-3.x-git.js.

Do you have some tests you could invoke on that pre-release version?

Summary of the most risky changes:

• removal of Sizzle in favor of inlining the selector engine code within jQuery with a lot of removals of workarounds for legacy browsers - we have tests but there's always risk we removed too much
• implementing the focus jQuery event in IE via focusin and blur via focusout - this is because focusin & focusout native handlers are executed synchronously in IE while focus & blur are async; in other browsers, all 4 are sync

I guess the second part doesn't affect you since you don't support IE anymore?

The patch is just a testing one, removing the label until 3.7 is actually released. Also, the npm pre-release doesn't include a built copy of jQuery nor does it include the build tools so to test I cloned ​https://github.com/jquery/jquery.git into node_modules/jquery and built the 3.x-stable branch.

I've done the following the testing:

• qUnit tests in both firefox and jQuery
• Manual testing of the following pages
  • post list page
  • Taxonomy page
  • Media Library
  • Menus
  • Customizer
  • Shiny Updates for Plugins
  • Site Health
  • Profile editing

Overall, 3.7 looks good. Once it's released, I'm going to use this ticket to update jQuery.

@mgol Overall, I see no issue with 3.7. No objection here with your team releasing the update. Thank you for reaching out.

I share this sentiment. Thanks again for the courtesy ping. I think if anything, it's more likely we'll expose some outdated code that should be updated in WordPress. But where we are still a while out from our ​next release (tentatively scheduled for late August), there's plenty of time to uncover and fix any issues.

Adding needs-patch for when the new version is bundled and published.

A full list of changes in this release can be found on GitHub: ​https://github.com/jquery/jquery/compare/3.6.4...3.7.0.

For updating the jQuery version in WordPress, package.json and script-loader.php need to get the new version string.

(As jQuery 3.7 has now been released, I removed the "Run tests with jQuery 3.x-git in preparation for jQuery 3.7.0" part from the ticket's title.)
