[client-fetch] Create const runtime object from enum strings

[blouflashdb]

From:

      "ResourceType": {
        "enum": [
          "Car",
          "Bike",
          "Truck"
        ],
        "type": "string"
      },

I would expect something like this:

export const ResourceType = {
    Car: 'Car',
    Bike: 'Bike',
    Truck: 'Truck'
} as const;
export type ResourceType = typeof ResourceType[keyof typeof ResourceType];

instead of:

export type ResourceType = "Car" | "Bike" | "Truck";

My config:

import { defineConfig } from "@hey-api/openapi-ts";

export default defineConfig({
  input: "./swagger.json",
  output: {
    lint: "eslint",
    path: "src/clients"
  },
  plugins: ["@hey-api/client-fetch"]
});

Thanks for the suggestion @blouflashdb! I assume the issue is if you pass a string somewhere the compiler will show errors despite passing the correct value?
