`npm_version` for npm 7 support

Is there a way to setup the action to use npm 7?

What about npm_version: 7 like actually it’s done for node_version?

Just like we have an option to use node versions, we should also have an option to choose npm versions

Run npm install -g npm@7.11.2

npm ERR! 404  'npm@7.11.2' is not in the npm registry.

Solution

    - name: npm 7
      run: npm i -g npm@7 --registry=https://registry.npmjs.org
