Update changelog in guidelines/index.html

[mbgower]

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.

@kfranqueiro the anchor links to the definitions are not showing up in the preview (circa line 300). I'm assuming they will when published?

@alastc I've added this to the Errata for CFC column, just to make sure it is not overlooked. This is deviating from our process and is not even necessary, since this update to an appendix of the spec does not need to be part of the CFC process, but I thought it made sense to include in this process.. It has not been reviewed by anyone at this point.

I'm not sure what you're referring to near line 300 which is just data-includes in the source, but if you mean #dfn-* links they seem to work fine? I'm also not sure what is responsible for generating the preview/diff links in this PR's description but they don't seem to work. Try using this: https://raw.githack.com/w3c/wcag/changelog/guidelines/index.html

Meanwhile, separate question: I see this is removing content from the change log section; is that all stuff that specifically happened between initial drafts of 2.2 and its final publication?

Yes, thanks for the other preview.

Technically, EVERYTHING that remains in the change log from the original publication is stuff that happened between its initial drafts and final publication, but I have retained a single mention of each new SC that was added, along with any other adopted changes that were made in the spec after 2.1. I have also modified the preamble to try to make this clearer.
