[ENHANCE] Provide helm chart as OCI artifact

[jkroepke]

Is your feature request related to a problem? Please describe. It would be nice to provide the helm chart as OCI artifact.

Providing the helm chart as OCI artifact would have benefits for end-users, e.g. removes the required to configure the stakater helm repo or avoids to download the index.yaml on each deployment.

Describe the solution you'd like

You can use the GH Package Registry as OCI repository. For example:

      - name: Login to GitHub Container Registry
        uses: docker/login-action@v3
        with:
          registry: ghcr.io
          username: ${{ github.actor }}
          password: ${{ secrets.GITHUB_TOKEN }}

      - name: Push charts to GHCR
        run: |
          helm package deployments/kubernetes/chart/reloader/
          helm push *.tgz "oci://ghcr.io/${GITHUB_REPOSITORY_OWNER}/charts"

Describe alternatives you've considered Leave the current legacy approch as-is.

Additional context Let me know, if you need assistance here.
