chore: fix helm checks workflow for client rate limiter error (#63)

change to `helm install` instead of `ct install` to don't run into that error anymore because when using helm install (also on local Minikube) the chart (for instance for this PR #53) installs without error.
also: add an informational step to describe the node for more awareness about available resources in the future and upgrade some actions.
