Changelog filter in the docs is broken

Bug report

Long ago I wrote a script to filter changelog entries.

This worked until 3.10, but broke starting from 3.11:

• https://docs.python.org/3.10/whatsnew/changelog.html (see the inputbox at the top)
• https://docs.python.org/3.11/whatsnew/changelog.html (the inputbox is missing)

This is because JQuery was removed, probably when Sphinx was updated in:

• Update to Sphinx 7 #99380
• Remove dependency on jQuery sphinx-doc/sphinx#7405

Assuming that changelog filtering is still valuable, it should be rewritten using vanilla javascript.
