JTI Claim as a string instead of guid

[sachinsatav]

Summary

Latest Microsoft Identity Model package >7.0.0 and above no longer serializes Guid datatype ( see - https://github.com/AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet/blob/f5fef2269a6eea5ba52d707d7235acf6a504db9f/src/Microsoft.IdentityModel.Tokens/Json/JsonSerializerPrimitives.cs#L860-L924) and instead throws an exception -

System.InvalidOperationException: Something went wrong when creating the signed JWT. Verify your private key.
---> System.ArgumentException: IDX11025: Cannot serialize object of type: 'System.Guid' into property: 'jti'.

Hello, @laura-rodriguez! Could this issue be re-opened, because when switching to v8 these changes were lost.

[laura-rodriguez]

Thanks for the heads up @shimbor . It seems we forgot to port this change to the codegen templates.
