ci: deprecate old chart repo syncs (#2007)

This PR stops syncing the previous helm repo at
https://github.com/odigos-io/odigos-charts

The crds there are not relevant for long time, and the new helm repo is
available for 5 month to migrate. see [this blog
post](https://odigos.io/blog/helm-chart-repository-deprecation).

This PR completes the migration
