Renamed ServiceRegistry.clear() to ServiceRegistry.legacyClear(), where legacyClear() now includes a warning recommending developers to use sub-realms instead. Plus, updated the patch instructions so they actually work.
Fixed minor typo.
Updated ServiceRegistryTest to use sub-realms instead of relying on ServiceRegisry.clear() being invoked.
