Avoid linking to specific versions of docs hosted on RtD

Instead, use URLs that redirect to the project's default version. This
gives the project more flexibility. For example, most of the time,
the default version might be stable, but if a critical documentation fix
is pushed to master, the default may be temporarily switched to latest.
