Workflow to deprecate more old packages in NPM

[gonzaloriestra]

WHY are these changes introduced?

We want to deprecate @shopify/shopify-cli-extensions and @shopify/ngrok in NPM.

WHAT is this pull request doing?

Adds a one-time GitHub action to deprecate the packages in NPM, by using the npm deprecate command.

That will include a warning in the NPM website and the command line when installing them: https://docs.npmjs.com/using-deprecated-packages

It can be reversed.
