Sync versionadded and versionchanged from draft into 2022.12

[thomasjpfan]

PR #585 added the versionadded and versionchanged admonitions to the draft website. Can they be synced up with the 2022.12 site?

I think this is reasonable. @steff456 would you mind opening another PR backporting the changes to the 2022.12 spec revision?
