Swift Language is missing

[p-brito]

SearchRepositoriesRequest.Language does not have Swift. @mislav @anaisbetts @zeke @mislav @zerowidth Can you please add this language, it's a quick fix I think.

@shiftkey I think this is a quick fix, can you handle it?

@p-brito please don't at-mention a whole bunch of people - some of whom no longer work at GitHub, none of whom are previous contributors to this project - and ask them to do this work.

I've merged #2344, so this will go out with the next release.

Thank you @shiftkey! Sry for tagging a lot of people.
