Add a GoReleaser release action

This will build the tool CLI binaries and package them on release.
For folks not writing Go libraries and just want the tools, this
should make using them easier.

This of course isn't the best means of distribution since there is
no Google signature of the releases, and no provenance attestation,
but it can at least be confirmed through a GitHub authenticated channel.
