Swagger 2.20.3 and other versions do not have proper CodeGen models for API responses

[ranilian]

When you download the Client SDK for typescript-fetch and attempt to use it in a standard application, the API responses' models don't match to the fetch requests being made primarily due to case issues:

For example this code expects the Endpoint response to include "id" but the server returns "Id"

const endpointsClient = new EndpointsApi(
  {
    apiKey: Config.PORTAINER_API_KEY,
  },
  Config.PORTAINER_URL + "/api",
  fetch
);
const environmentName = `${currentUser.username}/${new Date().toISOString()}`;
const environment = await endpointsClient.endpointCreate(
    environmentName,
    4,
    "",
    Config.PORTAINER_URL
  );
console.log(environment.id); // => returns undefined
console.log(environment.Id); // => returns the correct value if updated in the model otherwise this throws a Property 'Id' does not exist on type 'PortainerEndpoint'. Did you mean 'id'?

I believe something is wrong in the CodeGen output or I am using Swagger incorrectly.

Thank you!
