playground: simplify latest go version logic
This changes the build process to use a newly-added latestgo command for
determining the latest version of Go. This simplifies the Cloud Build
deploy.json significantly.
latestgo fetches the latest supported Go releases from maintner,
returning the first one. The maintner API always returns at least 2
releases on success, with the first result being the latest supported Go
release.
Updates golang/go#32606
