[Proposal] Function example for Go MongoDB CRUD that can be locally tested

[bymi15]

I created a easy-to-use Go MongoDB CRUD API with Netlify Functions and it would be great to add this to the examples.

Project repo: https://github.com/bymi15/go-mongo-serverless-crud-boilerplate

This also allows Go serverless functions to be executed and debugged locally (something that isn't currently supported by Netlify Dev).

I believe this will be useful for developers to easily set up and deploy Netlify functions with the Go MongoDB stack.
