Derive testArch from a Ready, schedulable node.

testArch becomes the kubernetes.io/arch selector for both the BuildConfig and CatalogSource. .items[0] can select a cordoned or NotReady worker, while an empty result falls back to runtime.GOARCH. This can leave the build or catalog pod Pending when no schedulable node has that architecture. Do not assume dedicated worker nodes. Handle the absence of a suitable node explicitly.

In `@tests-extension/test/qe/specs/olmv0_custom_schema.go` around lines 62 - 72,
Update the architecture discovery logic around the worker-node query to select a
node that is Ready and schedulable, using its kubernetes.io/arch value rather
than assuming .items[0] or dedicated worker nodes. Keep testArch set only when a
suitable node is found; otherwise handle the absence explicitly instead of
silently relying on runtime.GOARCH, and preserve the existing logging for
detection or fallback.
