feat: add Github CI action to automatically deploy tari-dan npm packages (typescript bindings, client libraries, etc) to the npm registry.

It will likely need a secret token configuration on the tari-dan repo: https://docs.github.com/en/actions/publishing-packages/publishing-nodejs-packages

Ideally it should not push a new version if nothing has changed. It may be ok for us to manually set a new version number to trigger a publish - might be better for managing semantic versioning. Maybe this is useful https://github.com/marketplace/actions/version-check
