Description of Change

This change calls datastore:commit() every time a Hue Bridge API key is captured/modified/removed. This is an API that's gated behind a SmartThings controlled allowlist, so it will not currently work until the Hue driver has been added to the allowlist. But I have tested that it does not cause a crash or issues with the driver's operation in any way, so the change is safe.

Summary of Completed Tests

Real device developer testing has been performed.
