System.UInt32 incorrectly translated to OpenApi format "int32"

1

A `int32` can not fit all possible values of a `uint32`. This leads to errors with generated clients. See [TypeExtensions.cs](https://github.com/microsoft/OpenAPI.NET.CSharpAnnotations/blob/5adf95d7b374f3547bc071c03158f54c62380d0f/src/Microsoft.OpenApi.CSharpAnnotations.DocumentGeneration/Extensions/TypeExtensions.cs#L25) Basically the same issue as #210, but with `uint` instead...
