Update changelog in guidelines/index.html (#4123)

Updated changelog to only record changes made that were preserved
through WCAG 2.2's Oct 2023 publication.
Added normative errata to the change log incorporated into the
republication
**NOTE** @iadawn, I took a guess on the actual republication date of Nov
15, which will need to be updated to match the real date.
