Remove deprecated RenameActorReminder methods

[ItalyPaleAle]

The RenameActorReminder methods have been removed in the runtime for Dapr 1.13. The methods need to be removed from the SDK.

See dapr/dapr#6945

In most SDKs, methods shouldn't be outright removed, but should return an error saying the method is not implemented instead, to prevent compile-time errors.

Marking this issue as closed as the SDK never implemented RenameActorReminder in the first place.
