Add new featuregate test to check if desired.Architecture is set as intended

A new featuregated field was introduced a while ago under clusterversion status -
`desired.Architecture` which denotes the architecture of the release
image being reconciled to. As we plan to promote the feature gate to
default - this adds a basic test to check if the `desired.Architecture`
is set based on the `release.openshift.io/architecture: multi`
being present as part of the release metadata.
