General Availability of Snapshots

[Snapshots](https://learn.microsoft.com/azure/azure-app-configuration/concept-snapshots) in App Configuration are now Generally Available. With snapshots, App Configuration provides solutions for scenarios like,

* Last known good configuration (easy configuration roll-back)
* Auditing (keep the released version of configuration unchanged or/and a history of released configuration' versions as Snapshots)
