Added NestJS examples

[thachp]

This is a work in progress.

Thank you for this MR, but I cannot accept it in this form.

• The e2e tests are now failing because the Express sample app is now in a different location.
• another package.json with own dependencies was introduced
• if already a NestJS example is introduced, the existing Express example should not be called example, but express.
• The coding conventions of this project (eslint, editorconfig, etc) were not followed.
• ...

I will provide a complete running NestJS example (and maybe a NestJS TSX module) soon.
