release: update patch release template
Created by: ggilmore
This PR changes the templates in the release tool to have Buildkite URLs that point to the specific MAJOR.MINOR.PATCH builds instead of the generic MAJOR.MINOR build.
For example, the buildkite urls for the 3.27.4
patch release used to only point to the 3.27
branch:
https://buildkite.com/sourcegraph/sourcegraph/builds?branch=3.27
...
Which was never the build status that you cared about. Now, they'll point to the specific release candidate
https://buildkite.com/sourcegraph/sourcegraph/builds?branch=v3.27.4-rc.1
...
and the correct tag for the final build:
https://buildkite.com/sourcegraph/sourcegraph/builds?branch=v3.27.4
