feat: allow disabling test connection

[HenkvanDyk]

Summary of changes:
The base test connection which is created when doing a helm create is included in this chart.
While useful, it is not always required and optionally disabling it is useful.

Checklist:

• I updated the artifacthub.io/changes annotation in Chart.yml according to the documentation
• Optional: I updated in README.md the Helm Values

Hello @HenkvanDyk

Helm is only executing the tests manually via helm test not when installing the chart.
I don't think this is necessary or it is only for not rendering the template but I don't see cases.

[HenkvanDyk]

My use case - we have linting checks which ensure that any resources which are created are tagged with specific pod labels.
I can ask my team to update the linting rules to skip any linting rules on resources with annotation "helm.sh/hook": test, or otherwise I'd like to include the podLabels in the same way they are created in other pod spec templates.

By podLabels you mean the deployments labels ? Common labels are already added to test.

metadata:
  name: "{{ include "ollama.fullname" . }}-test-connection"
  namespace: {{ include "ollama.namespace" . }}
  labels:
    {{- include "ollama.labels" . | nindent 4 }}

@jdetroyes correct, but they cannot be extended like they can in deployments.
I've added the ability now.

Hello @HenkvanDyk,

Can you fix the linter before merging?

Thanks!
