Description

After upgrading the API version of ACR to 2025-11-01, there are a few new properties introduced:

• network_rule_bypass_allowed_for_tasks: This is a new policy setting being introduced allowing customers to opt-in to network bypass for tasks. See: https://learn.microsoft.com/en-us/azure/container-registry/manage-network-bypass-policy-for-tasks. Whilst, there is an issue with this attribute ([BUG] ACR 2025-11-01 GET won't return networkRuleBypassAllowedForTasks Azure/azure-rest-api-specs#40126), so I didn't support it in this PR until the issue is resolved.
• azuread_authentication_as_arm_policy_enabled: Microsoft Entra tokens are used when registry users authenticate with Azure Container Registry (ACR). By default, Azure Container Registry (ACR) accepts Microsoft Entra tokens with an audience scope set for Azure Resource Manager (ARM), a control plane management layer for managing Azure resources. See: https://learn.microsoft.com/en-us/azure/container-registry/container-registry-disable-authentication-as-arm
• role_assignment_mode: See: https://techcommunity.microsoft.com/blog/appsonazureblog/azure-container-registry-repository-permissions-with-attribute-based-access-cont/4467182

The default values are set per the API behavior (manually checked) and API spec definition.

Additionally, I've removed the checkNameAvailability API call during the Create function, which has no obvious benefit and is now failing with 503:

{
  "error": {
    "code": "ServiceUnavailable",
    "message": "Unable to perform post/subscriptions/checkNameAvailability. Please try after some time."
  },
  "status": "Failed"
}
