Fix min kube version validation

[kutluhanmetin]

Fixes operator-framework/operator-sdk#5995
operator-sdk bundle validate passes all tests when CSV's spec.minKubeVersion with version format x.y. However spec.minKubeVersion with format x.y should be invalid because OLM refuses to deploy the CSV. Basically, this PR adds a validation method validateMinKubeVersion that validates if version format is in semantic versioning x.y.z. So that operator-sdk bundle validate fails before OLM refuses to deploy.
