To create a new version of the package, we run the following command manually:
$ npm version [major|minor|patch]
This will bump the version in the package.json and package-lock.json files, commit it to git and tag it with the same version.
If we push this using:
$ git push origin main --follow-tags
both the commit and the tag are pushed and the Github Actions workflow will kick in to publish the package to the NPM Registry.
