Fix typos in documentation and comments (GH-102374)

Found some duplicate `to`s in the documentation and some code comments and fixed them.


[Misc/NEWS.d/3.12.0a1.rst](ed55c69ebd/Misc/NEWS.d/3.12.0a1.rst) also contains two duplicate `to`s, but I wasn't sure if it's ok to touch that file.  Looks auto generated.  I'm happy to amend the PR if requested. :)
