[Feature Request] Build Helm chart and push it to OCI registry

[froblesmartin]

Is your feature request related to a problem? Please describe.

Usually all Helm Charts and built/packaged and pushed to an OCI registry. Easily you could just use GitHub Packages which is free for public packages: https://docs.github.com/en/billing/managing-billing-for-github-packages/about-billing-for-github-packages#about-billing-for-github-packages, or you could apply for Docker's program: https://www.docker.com/community/open-source/application/

In this way, people could just replicate the Helm chart or use it directly instead of cloning the git repository and having to download the dependencies.

Describe the solution you'd like

Get a pipeline in the repository to package the Helm Chart and publish it to any public OCI registry.

Additional context

I could contribute with a PR to add the pipeline. :)
