Use GitHub Container Registry to Store Helm Chart (#44)

Instead of building and uploading the Helm Chart for the parca-operator
to the https://github.com/ricoberger/helm-charts repository, we are now
using the GitHub Container Registry to store the Helm chart.

Starting with the new version 1.0.0 the Helm chart will only be
available at ghcr.io/ricoberger/charts/parca-operator.
