[FEATURE] Provide credentials to npm trough environment variables

[Kuinox]

What / Why

Today the only way to give npm the PAT to push packages is to add the PAT in the .npmrc.
In order to authenticate, our CI must inject the credentials in the .npmrc, then revert the change when the operation is done.
It would be far better if we could give credentials to npm directly via environment variables, so we can stop using this "workaround".
