rust: fix highlight corner-cases

* add punctuation highlights for commas as in function parameters
* remove stray `variable.parameter` highlight
    * I couldn't find any regressions from this and it fixes an
      edge case I ran into (but sadly did not record 😓)
* highlight `fn` as `keyword.function`
    * the theme docs have `fn` as an example so it seems fitting
