[BUG] In-Memory Provider throws exception

[askpt]

Observed behavior

The InMemory provider is throwing an exception here:

dotnet-sdk/src/OpenFeature/Providers/Memory/InMemoryProvider.cs

Line 115 in 4563512

throw new TypeMismatchException($"flag {flagKey} is not of type {typeof(T)}");

.

We should move from throwing exceptions to returning an ErrorType with a default value. Something like:

return new ResolutionDetails<T>(flagKey, defaultValue, ErrorType.TypeMismatch, Reason.Error, $"flag {flagKey} is not of type {typeof(T)}");

Expected Behavior

The In Memory provider doesn't throw any exceptions, and all unit tests pass.
