[enhancement] Publishing GitHub Package

[galimba]

Hi, would it be possible to release a GitHub package with the repository?
The main motivation would be to allow other devs to consume the contracts as a package.json dependency.
Something similar to:

npm install @hermeznetwork/contracts@1.0.0
or
"@hermeznetwork/contracts": "^1.0.0"

More info on how to do this: https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-npm-registry

Best,
Galimba
