Do we know why we needed the testdata changes?

[fridgepoet]

Seems there was some change in the "experimental" package of github.com/grafana/grafana-plugin-sdk-go which generated the expected json response during the update to v0.159.0

So the re-generated expected response includes the change. Let me know if we're not comfortable just going with this; I believe it's not strictly necessary for me to update grafana-plugin-sdk-go.
