rustdoc: stabilise --default-theme command line option

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.)

There is also a commit to do some minor grammar fixes to the help message.
