sign-launcher: make the help text more automatic

Browse Source 
Rather than display "3.0" all the time and confuse people, extract
the version from the launcher we're signing and display that.

Also reformat the text to follow our current practice: upload the
versioned launcher by itself first, and then later copy that over
the default.

And while we're here, add tips for rollbacks.

Repo launcher bucket:
gs://git-repo-downloads/
To upload this launcher directly:
gsutil cp -a public-read {opts.launcher} {opts.launcher}.asc gs://git-repo-downloads/
You should first upload it with a specific version:
gsutil cp -a public-read {opts.launcher} gs://git-repo-downloads/repo-{version}
gsutil cp -a public-read {opts.launcher}.asc gs://git-repo-downloads/repo-{version}.asc
NB: You probably want to upload it with a specific version first, e.g.:
gsutil cp -a public-read {opts.launcher} gs://git-repo-downloads/repo-3.0
gsutil cp -a public-read {opts.launcher}.asc gs://git-repo-downloads/repo-3.0.asc
Then to make it the public default:
gsutil cp -a public-read gs://git-repo-downloads/repo-{version} gs://git-repo-downloads/repo
gsutil cp -a public-read gs://git-repo-downloads/repo-{version}.asc gs://git-repo-downloads/repo.asc
NB: If a rollback is necessary, the GS bucket archives old versions, and may be
accessed by specifying their unique id number.
gsutil ls -la gs://git-repo-downloads/repo gs://git-repo-downloads/repo.asc
gsutil cp -a public-read gs://git-repo-downloads/repo#<unique id> gs://git-repo-downloads/repo
gsutil cp -a public-read gs://git-repo-downloads/repo.asc#<unique id> gs://git-repo-downloads/repo.asc
