The CognitoPreTokenGenerationV2Event does not adhere to the AWS documentation

Discussed in https://github.com/aws/aws-lambda-dotnet/discussions/1792

^{Originally posted by DizzyDeveloper August 19, 2024} According to the the AWS documentation for the Pre token generation Lambda trigger the claims response of the CognitoPreTokenGenerationV2Event should be able to accept any one of [String, Number, Boolean, Array of strings, numbers, booleans, or a combination of any of these, JSON]. However, at the moment it just accepts a string map? Is there any intention implement the documented specs?

Note, I did a hack around locally by cloning the CognitoPreTokenGenerationV2Event and updating the signature of ClaimsToAddOrOverride property in the AccessTokenGeneration class from:

public Dictionary<string, string> ClaimsToAddOrOverride { get; set; } = new (); to public Dictionary<string, object> ClaimsToAddOrOverride { get; set; } = new ();

and that works. Can something similar be done as part of this repo.

Looks like Java version and Go version have the same issue.
