Description of the problem:

When creating a subscription for a Helm chart it is possible to set a packageFilter and version to select a specific Helm chart version. If that version starts with a character instead of a number RHACM does not deploy the application. Removing the filter allows it to deploy.

Release version:
2.4

OCP version:
4.9.8

This works (note version is 0.18.0):

            enabled: true
            raft:
              enabled: true
          affinity: ''
          image:
            repository: registry.connect.redhat.com/hashicorp/vault
            tag: 1.9.0-ubi
          updateStrategyType: "RollingUpdate"
        injector:
          authPath: auth/ocp-local

          agentImage:
            repository: registry.connect.redhat.com/hashicorp/vault
            tag: 1.9.0-ubi
  packageFilter:
    version: "0.18.0"
  placement:
    placementRef:
      kind: PlacementRule
      name: vault

This does not (version v1.6.1). Removing the package filter makes it work.
