Links to fragments (bookmarks) in
batch-spec-yaml-referencewere incorrect: they contained dashes where dots are in the headings, but the bookmark generator (GithubSlugger) creates ids by removing alpha-numeric characters and encoding spaces as dashes, so the links with dashes where there were dots didn't work.Remove all dashes; spot test the links.
Also did some general fixup of
batch-spec-yaml-referencelinks, where the dashes were underscores, and fixed a redirector that was directing to the wrong location.Tacked on a similar fix in
