rustdoc: stabilise --default-theme

Browse source 
As discussed in #77213, this seems like it has bedded in and can be
safely and usefully made stable.

(rustdoc already has other stable options that interact quite
intimately with the rustdoc-supplied CSS, and also an option for
supplying entirely different CSS, so exposing the theme names this way
seems a very minor step.)
