Gatsby: [docs] add page in contributing section on building reproducible builds

[lannonbr]

Summary

A notice when filing a bug report here is to create a demo project to show off the bug. I think it would be useful to either enhance the "How to file an issue" page or create a new page describing how to create a reproducible build and the benefits of it.

Motivation

It would be good to have a page describing further how to make a demo project for such.

Would someone on the @gatsbyjs/docs team be interested in a pair session to tackle this with me?

Hey @lannonbr, I like that idea. There is some new stuff in the Code Contributions page on setting up Wordpress with Docker that I figured would get expanded for other setups...so my question is, would this content be a good fit there (with a link from "how to file an issue"), or on a separate page?

FWIW people can launch a demo project in codesandbox but this is not documented on the docs.

That would be a great addition too!

So what I was thinking was more the idea to focus on more of what is a reproducible build is and how it is helpful for developers to debug down to figure out a possible solution so there is as little surface area to debug, but yeah I think this would be a good page to link from the "how to file an issue" and have a page describing reproducible builds

That sounds good to me @lannonbr. I'd say if you're up for writing it, go for it! And thanks for the suggestion!
