Implement script for publishing automatically the tarball in the GitHub repo

[viferga]

This script must tag properly and get all history of all commits, probably run a make download too. This script should be implemented here:
https://github.com/metacall/distributable/blob/52008d9afefdda7db2fa827bcd29d883e19fad79/tools/release.sh

Probably we can use this template to implement the tokens for GitHub:
https://github.com/metacall/distributable/blob/52008d9afefdda7db2fa827bcd29d883e19fad79/.netrc.template

This script is needed in order to implement CI/CD for MetaCall Distributable.
