.github/workflows: Fix the release quickstart.yaml GH action

Update the .github/workflows/quickstart.yml github action and replace
the usage of `kubectl wait ...` with a function that waits until the
various OLM component deployment resources are present and reporting an
available status.

Using `kubectl wait ...` is potentially problematic as it doesn't
support waiting until the creation of that resource, so in the case the
PackageServer deployment doesn't exist yet as the catalog/olm operators
are still being setup, this action will fail as `kubectl wait ...` will
return a non-zero exit code.
