* fix(ts): correctly export sub-module types (#1677)

* chore(types): build types script

Adds a script that moves the declaration files we have in `./types` to `./dist` relative to the files they intend to type.

This is the first step, we still need to change what we declare in `package.json`, add the script to the CI pipeline if we're happy with it and figure out how to type `next-auth/jwt`.

* fix(ts): add .d.ts sub-module files to package.json

 ### TypeScript
 
-You can install the appropriate types via the following command:
+NextAuth.js comes with built-in types. For more information and usage, check out the [TypeScript section](https://next-auth.js.org/getting-started/typescript) in the documentaion.
 
-```
-npm install --save-dev @types/next-auth
-```
-
-As of now, TypeScript is a community effort. If you encounter any problems with the types package, please create an issue at [DefinitelyTyped](https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/next-auth). Alternatively, you can open a pull request directly with your fixes there. We welcome anyone to start a discussion on migrating this package to TypeScript, or how to improve the TypeScript experience in general.
+The package at `@types/next-auth` is now deprecated.
