nixos-render-docs: add the .keycap class

Browse Source 
this lets us parse the `[F12]{.keycap}` syntax we recently introduced to
the nixos manual markdown sources. the docbook renderer emits the keycap
element for this class, the manpage renderer will reject it because it's
not entirely clear what to do with it: while html has <kbd> mandoc has
nothing of the sort, and with no current occurences in options doc we
don't have to settle on a (potentially bad) way to render these.
