Migrate Azure module to azure.azcollection (#14909)

* Migrate Azure module to azure.azcollection

Replace deprecated azure_rm_deployment module with FQCN:
- azure_rm_deployment → azure.azcollection.azure_rm_deployment

Changes:
- Add azure.azcollection (>=3.0.0) to requirements.yml
- Update roles/cloud-azure/tasks/main.yml to use FQCN

No parameter changes needed - the collection module supports all
existing parameters via aliases (deployment_name, resource_group_name,
client_id, secret, tenant, subscription_id).
