Description of problem:

Typical CD tools handle Helm Charts by rendering the Helm templates (`helm template`) and applying them against the target cluster.
But right now, the RHDH must-gather tries to detect Helm-based instances by running `helm list`, which in this case, doesn't return anything because there is no deployed Helm release.

Steps to Reproduce

• Deploy Helm-based instance, but by manually rendering the templates and applying, e.g:

helm template my-app oci://quay.io/rhdh/chart | oc -n my-ns apply -f -

Then run the RHDH must-gather tool.

Actual results:

No Helm release found.

Expected results:

The must-gather should detect this kind of deployments of RHDH, as this is still using the Helm Chart (supported installation method), but without leveraging the Helm CLI or OCP web console.

Reproducibility (Always/Intermittent/Only Once):

Always
