Typo in PersistentVolumeClaim resource name in the `clusterResource` analyzer

[diamonwiggins]

Bug Description

In the clusterResource analyzer, when using kind: PersistentVolumeClaim it fails with:

Analyzer Failed

failed to find resource: failed to find resource

This is due to a typo in the resource names for the clusterResource analyzer here - https://github.com/replicatedhq/troubleshoot/blob/main/pkg/analyze/kube_resource.go#L25. The key name is incorrect which is what causes the issue.

Expected Behavior

Using kind: PersistentVolumeClaim should not result in an error

Steps To Reproduce

    - clusterResource:
        checkName: Check PVC is RWX
        kind: PersistentVolumeClaim
        name: pvc-name
        namespace: some-namespace
        yamlPath: "spec.accessModes.[0]"
        expectedValue: ReadWriteMany
        outcomes:
          - fail:
              when: "false"
              message: The user provided PVC does not support ReadWriteMany (RWX) access mode.
          - pass:
              when: "true"
              message: The user provided PVC supports ReadWriteMany (RWX) access mode.
