Logically re-apply 7afaacf9a8 ("doc: fix link to kodi-19.0 announcement"),
because it was lost in the conversion from docbook to markdown, in commit
32c2dd304d ("docs: nixos release notes to CommonMark (2105)").
(Hm, apparently we have *both* docbook and markdown? CI failed before I
updated the .xml file.)
