Support private npm packages

[timiyay]

I trialled this Github Action, but am unable to pass the yarn install stage since we can't access our private npm packages.

Does this action support any way of passing this token, or, is there a complimentary Github Action that can be used to make this available?

We have made it work by adding this step before:

- name: Setup Github Package Repository access token
  run: echo ${{ secrets.GITHUB_NPM_TOKEN_FULL }} > ~/.npmrc

And add a secret GITHUB_NPM_TOKEN_FULL that looks like this:

//npm.pkg.github.com/:_authToken=MY_TOKEN

The same would work, I presume, with a private npm registry.

Thanks for the suggestion @mydea. That works out for us.

I should've done some more research to understand how Github Action steps can be composed. They're somewhat new to me, and the other JS actions I'd used would take NPM_TOKEN in env, so I was wondering if this action did too.

I'll close this, since it can be solved without adding code to this repo.
