Fix Snapshot_command_supports_managementGroup_scope test CI failure (#19365)

The `Snapshot_command_supports_managementGroup_scope` integration test
was failing in CI because its expected JSON was missing the `"outputs"`
field that the snapshot command now includes in its output.

- Added `"outputs": {}` to the expected JSON assertion in
`SnapshotCommandTests.Snapshot_command_supports_managementGroup_scope`,
consistent with all other snapshot test assertions in the file
