.github,go/utils/{publishrelease,rpmbuild}: Add a basic RPM build to the published release artifacts for Dolt.

These RPMs include the statically linked Dolt binary, installed at
/usr/local/bin/dolt. They work on x86_64 and aarch64 RPM-based Linux
distributions. To install them, download the appropriate
`dolt-...-1.{x86_64,aarch64}.rpm` file from the GitHub release artifacts and
run `sudo rpm -i downloaded_file.rpm` on it.
