NestJS example

I was doing code spring cleaning, and ran into my NestJS example project for working with EdgeDB.

https://github.com/tdolsen/edgedb-nestjs-example

Any interest in getting this cleaned up and merged into this repo? I'll gladly make some changes if need be, to get it to an acceptable state.

Start by reviewing the linked NestJS example project and comparing it with the existing examples in this repository. Determine what cleanup and integration work would make the example acceptable for inclusion; done means the cleaned-up example is merged into gel-examples.
