Well, if we had marking for "theme with variant", then we'd know which
themes are "the same", but with a variant.

So your command could instead be `theme-choose-variant', but since
there's only two variants here, it'd toggle.  If there were more, the
user would be prompted for which variant to use, which would cover
gruvbox, which Stefan mentioned.

And in addition, this tagging could be used for automatic dark/light OS
changes, so it's at least three birds with one stone.
