Update thirdparty jQuery libraries

[emteknetnz]

There are unmanaged jquery libraries in the thirdparty directories such as jquery-entwine.

ACs

• jquery libraries in the thirdparty directories need to be updated to work with jQuery 3.6.0+
• Behat on silverstripe/installer is green

Stretch goal

• Migrate from thirdparty folder to be regular npm dependencies that get built with yarn build

Notes

• This need to be targetted to the 4 branch and will be released in 4.12

I have spun off some of the jQuery library upgrades as separate cards since they can (and in some cases must) be done separately:

• Update jquery-cookie from the thirdparty folder #1376
• Update jstree from the thirdparty folder #1377

Note: While working on this I have also run into existing console errors that were caused by the following issues

• Invariant package JS warning on page publish silverstripe-elemental#950
• CMS 4.12: console error for any page with an elemental area (due to gridfield js) #1385
