Setup Workflow Process for Automatic Release to Rubygems on New Tagged Release

[unicodeveloper]

We need to create a workflow GitHub action that can automatically run to release a new version on Rubygem when I tag a new release on GitHub.

The PHP, Kotlin, Java, Python and .NET SDKs automatically publishes when I tag a new release on the GitHub repo.

E.g if I tag v2.0.0, a Github action should run that authenticates with the Novu account on rubygem and publishes a new release.
