Please prepare bundle for OCP 4.5

[Tim Bielawa]

Now that we are fully branched for 4.5, please prepare your operator to supply a 4.5 bundle, so that 4.5 operator publishing works and doesn't overwrite 4.4 bundles. This means at least updating the package.yaml under https://github.com/openshift/ptp-operator/blob/master/manifests/ptp-operator.package.yaml

Reference: Get OLM operator owners to update their CSV channels
