Mention tsconfig-paths for codegen.ts?

### Which packages are impacted by your issue?

### Describe the bug

If you are using a `paths` section in your `tsconfig.json`, the `codegen.ts` config will fail to load if it exports any code from your project. This can happen, for instance, if you are using Pathos, which recommends providing the scheme as a string to the config.

```bash
❯ npm run gql-codegen

> gql-codegen
> graphql-codegen

TypeScriptLoader failed to compile TypeScript:
Cannot find module '@lib/model-settings'
Require stack:
- /Users/artyom/code/windorg/woc/lib/graphql/schema/user.ts
- /Users/artyom/code/windorg/woc/lib/graphql/schema.ts
- /Users/artyom/code/windorg/woc/codegen.ts
- /Users/artyom/code/windorg/woc/node_modules/cosmiconfig-typescript-loader/dist/cjs/index.js
- ...
```

The solution is to add this section to your `tsconfig.json`:

```json
"ts-node": {
"require": [
"tsconfig-paths/register"
]
}
```

And install `npm i -D tsconfig-paths`.

I suppose this could be mentioned in the getting-started guide, but I don't know where in particular.
