[ACR] az acr connected-registry resync: Add command to manually trigger a sync from the parent registry

az acr connected-registry resync

Description

Adds a new command that issues a manual sync request to a connected (on-prem) registry from its parent cloud registry. Wraps the existing ConnectedRegistries.resync SDK operation (API version 2026-01-01-preview).

The call is synchronous and returns the updated ConnectedRegistry resource. The actual data transfer is performed asynchronously by the on-prem agent, lastSyncTime updates only after the agent reports completion. The next sync result will show syncTrigger: ManualResync.

Testing Guide

az acr connected-registry resync \
    --name <myconnectedregistry> \
    --registry <mycloudregistry> \
    --resource-group <rg>

# Subsequent show confirms the trigger:
az acr connected-registry show \
    --name <myconnectedregistry>  \
    --registry <mycloudregistry> \
    --resource-group <rg> \
     
# -> "parent.syncProperties.registrySyncResult.syncTrigger" = "ManualResync"

Recorded test (test_acr_connectedregistry) asserts expect_failure=True because the test registry has no on-prem agent attached, so the service returns ConnectedRegistryHasOfflineChildren. This still validates that the CLI command is correctly registered and accepts the right arguments.
