Can't deploy helm chart when artefact file name is different than chart name

[wim1988]

What happened?

I wanted to deploy a helm chart into my vCluster, but vCluster was logging the error:
ERROR deploy/start.go:42 Error deploying manifests: couldn't find chart {"component": "vcluster"}

What did you expect to happen?

vCluster installs the specified helm chart.

How can we reproduce it (as minimally and precisely as possible)?

Specify a helm release like this:
...

• chart:
  name: strimzi-kafka-operator
  repo: https://strimzi.io/charts
  version: "0.41.0"
  ...

vCluster will download and store the chart in its working directory as strimzi-kafka-operator-helm-3-chart-0.41.0.tgz.
Then it will fail with the error I mentioned. If I manually enter the vCluster pod and rename the file to strimzi-kafka-operator-0.41.0.tgz, it continues and succeeds.
This is because it only works, if the downloaded artefact name equals the specified helm chart name. I checked your code and this seems to be the issue.

Anything else we need to know?
