Helm chart Ingress template incompatible with k8s < v1.18

[jlukenoff]

I'm excited to start using Marquez but have found that the Ingress template in the current Helm chart is incompatible with recent versions of kubernetes (I'm running 1.22). The main problem I'm running into right now is the apiVersion has been updated to networking.k8s.io/v1 vs extensions/v1beta1 that is in the template today. This results in a the server could not find the requested resource error when attempting to install the helm chart. There are also some other minor changes to the schema.

Fortunately, it's pretty simple to update the template to be back-compatible. I'd be happy to pick this up.
