Bug description:
OSM CLI build has been failing occasionally with the following error:

helm dependency update charts/osm
Getting updates for unmanaged Helm repositories...
...Unable to get an update from the "https://charts.bitnami.com/bitnami" chart repository:
Error: no cached repository for helm-manager-54d2620bbb6f1bb3f35d4c7f945bfa25077949488dcbb0a4d01c90f2c35baa59 found. (try 'helm repo update'): open /home/runner/.cache/helm/repository/helm-manager-54d2620bbb6f1bb3f35d4c7f945bfa25077949488dcbb0a4d01c90f2c35baa59-index.yaml: no such file or directory

The helm dependency update command used in the Makefile fails when it shouldn't.

In a single CI run, I can see that command both pass and fail, which gives me the impression there's not much we can do here besides working around needing to run helm dependency update at all.

Is it possible to remove the need for helm dependency update?

Checking in charts/osm/charts seems like it would work, but I'm not 100% sure.
