doc: fix missing changelog corrections

There was a slight discrepancy between the build of 12.16.1 and what
landed on 12.x. This was only a couple spelling errors that didn't
get updated between machines I was working on. This change gets the
changelog up to date with what went out in the release vs what is
current on the 12.x release branch.
