This commit introduces a new template repository for creating custom HTML elements for the core web3 framework. The template includes a Go backend, an Angular custom element, and a full release cycle configuration.
The Go backend is a simple HTTP server that serves the frontend and provides a basic API. The Angular custom element is a simple "Hello, world!" component that can be used as a starting point for more complex elements. The release cycle is configured with GoReleaser and GitHub Actions.
