Fix helm tests (#827) (#828)

This is a backport of PR #827 as merged into main (c8a33c7).
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.
