Allow actions to specify target registry domain to publish

[rayriffy]

At the moment GitHub Actions will create .npmrc that only point to default's NPM registry (which is registry.npmjs.org). This actions option will allow user to change registry domain that script will create, and configure.

Hey @ImadBoumzaoued, we need this feat to be able to define a custom registry url. Can you merge this, plz!!?

[Andarist]

We only create .npmrc if there is none already. The preferred solution to this is to include a preparation step like this one:

- name: Creating .npmrc
  run: |
    cat << EOF > "$HOME/.npmrc"
      //registry.npmjs.org/:_authToken=$NPM_TOKEN
    EOF
  env:
    NPM_TOKEN: ${{ secrets.NPM_TOKEN }}

You can control your target registry in the .npmrc that you create.

That's right @Andarist, but I didin't need the home variable, just created with .npmrc path and works.

The only thing I think it's a little strange is the output from changeset warning me that doesn't exist a npm user file, even if I created an step before.

Otherwise, all good.
