manifests: Update generated CRD for LoadBalancerSpec zones

Update generated CRD manifests to include the availabilityZones field
on LoadBalancerSpec with proper validation:

- Type: array of strings
- List type: set (prevents duplicates)
- Max items: 3 (Azure supports up to 3 zones per region)

This is the result of running 'make generate-manifests' after adding
the AvailabilityZones field to the API types.
