Description of problem:
All Helm charts with a min kubeVersion specified (even if support pre-releases) in Chart.yaml are filtered from Developer Catalog.
Examples filtered from redhat-helm-charts repo :
1) ibm-cpq-prod which has following in Chart.yaml
2) ibm-operator-catalog-enblement which has following in Chart.yaml
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log into OCP 4.6 cluster
2. Switch to Developer Catalog
3. Click '+Add'
4. Click 'Helm Chart' tile
Only 2 helm charts appear (Nodejs & IBM Object Storage Plugin) - both don't contain min kube version, rest are filtered
All 6 helm charts in the redhat-helm-charts repo should be available for install : nodejs-ex-k, ibm-object-storage-plugin, ibm-cpq-prod, ibm-oms-ent-prod, ibm-oms-pro-prod, & ibm-operator-catalog-enablement
