🚀 Publish Go and Typescript types using 🧙 Mage

[bdeneux]

Building on the progress made in issues #25 and #27, we need to enhance our build system to include the ability to publish generated types. This will be achieved through the integration of the Mage build tool.

The proposed enhancements will require updates to our GitHub Actions workflow to accommodate the new publishing steps. The key objectives of this issue are:

1. Publish Go Types: We need to implement functionality to publish Go types and manage package version updates. This will involve creating a new Mage target that handles the generation and publishing of Go types, as well as managing the versioning of the Go package.

2. Publish TypeScript Types on npm: Similarly, we need to create a Mage target for publishing TypeScript types on npm. This target should handle the generation of TypeScript types and their subsequent publishing on npm.
