Backport to Stable-3: Fix helm tests (#827) and Fix helm integration tests (#830) (#829)

SUMMARY
Some of the charts we've used for testing are no longer available at the old helm repository urls, as they've been moved to oci registries. This updates those charts. In the longer term, we should find a better way to handle these kinds of test fixtures, probably by switching to local charts as much as possible.
