Improvements to the generated READMEs

[ms14981]

Taking the openapi-forge-typescript generator as an example, it creates a README.md with this:

import ApiPet from "./api";
import Configuration from "./configuration";
import { transport } from "./nodeFetch";
// import any model types you need
import { Order } from "./api/model";

const config = new Configuration(transport);
// set the base path for your endpoint
config.basePath = "https://example.com";
// set any environment specific configuration here
const api = new ApiPet(config);

api.findPetsByStatus(...).then((data) => {
   // log the result
   console.log(data);
});

1. It sets the basePath to "https://example.com". One of our CLI arguments is https://petstore3.swagger.io/api/v3/openapi.json and the base path is https://petstore3.swagger.io. Is it possible to include this in the README.md template to save the user having to manually switch it out?
2. Can we include an example status to put into api.findPetsByStatus?
3. Can we generate an example command to run? e.g. generate an index.ts as well as a README.md and tell the user that they can run it with ts-node?

It's possible that all of this is overkill, and given that the user will need to edit the code anyway, perhaps this isn't worth it?
