Bump Superset Version

@kgpayne I want to be able to bump the Superset version up, how do I go about doing that?

I see in Lens that the superset pods are running apache/superset:latest but it doesnt have the updates I get when I run latest locally. I'm wondering if our latest is out of date if we dont periodically pull for updates. At first I created meltano/infra/terraform@41f99662 to allow us to bump the chart version from the squared repo but now I'm not sure thats actually what im trying to do.
