This adds a new route at `/actions/workflows/{workflow}/runs/latest`,
which will redirect to the latest run of the given workflow. It can be
further restricted by specifying an optional `?branch={branch}` query
parameter. If no branch is specified, the route defaults to using the
repo's default branch.
This route is meant to go hand in hand with the Badge route that returns
the result of the same workflow as a badge. This route can be used to
link to the run that produced that result.
Fixes#2303.
