fix: reallowing nodeclaim zones to fix node/nodeclaim creations for workloads with zone affinity constraints

[comtalyst]

Fixes #339

Description See the issue. This change should not undo the continuous drift issue that https://github.com/Azure/karpenter-provider-azure/pull/274 fixes, as adding zones requirements is still prohibited on the nodepool CRD, which is the (intentionally) user-facing interface. Current drift logic also "ignore" requirements that exist in NodeClaims, but not NodePools.
