Marten ProviderUpdate and Persistence provider test (#2031)

* feat: Update Marten package version to 6.0.2

- Updated the Marten package version from 4.3.1 to 6.0.2 in the project file.
- Changed the access modifier of the `Event` and `Snapshot` classes from internal to public in the `Proto.Persistence.Marten` namespace.
- Replaced calls to `_store.OpenSession()` with `_store.IdentitySession()` in the `MartenProvider` class for consistency.
- Added new test cases for different providers (InMemory and Marten) in the `ExamplePersistentActorTests` class:
    - EventsAreSavedToPersistence
    - SnapshotsAreSavedToPersistence
    - EventsCanBeDeleted
    - SnapshotsCanBeDeleted
    - GivenEventsOnly_StateIsRestoredFromEvents
    - GivenASnapshotOnly_StateIsRestoredFromTheSnapshot
    - GivenEventsThenASnapshot_StateShouldBeRestoredFromTheSnapshot
    - GivenASnapshotAndSubsequentEvents_StateShouldBeRestoredFromSnapshotAndSubsequentEvents
    - GivenMultipleSnapshots_StateIsRestoredFromMostRecentSnapshot

* Refactor tests to use Sqlite provider

* Add support for additional persistence providers

This commit adds support for the following persistence providers:
- Couchbase
- DynamoDB
- MongoDB
- RavenDB
- SQL Server

It also includes changes to the ExamplePersistentActorTests class to test the functionality of these new providers.

* removed providers
