Comment that code was auto generated and should not be modified

[xddq]

@sinclairzx81 Hey!

I want to add a comment to the top of the generated typebox file with something like This code was auto generated, please don't modify it since changes will be lost on next generation to the typescript -> typebox part.

E.g.

/**
* Don't change this file! It was auto generated and changes will probably be lost with the next generation.
*
*/
import { Type, Static } from "@sinclair/typebox";

export type T = Static<typeof T>;
export const T = Type.Object({
  a: Type.Number(),
  b: Type.String(),
  c: U,
});

type U = Static<typeof U>;
const U = Type.Object({
  a: Type.Number(),
  b: Type.String(),
});

Do you think I should add this here, or rather add it inside the cli package ts2typebox?
