gh-pr-35015: Trac role to GitHub

### 📚 Description

Changes the `:trac:` role to point to github instead, and changes
deprecation and stopgap warnings.  Changes all the resulting urls that
are printed in doctests, as well as various comments in code.

Does not update the developer documentation to explain how to use
github.
