[docs] A doc on how to follow up with reviews after a PR

[urielhdz]

Summary

Create a guide to explain how to solve changes requests after a PR, these guide could be complementary to the How to Open a Pull Request guide that was published recently.

Motivation

After my first PR I received reviews from both the community and the core team and at first I didn't know how to address them, @marcysutton pointed out that GitHub allows you to resolve all reviews at once but the UI it is not very intuitive for beginners.

I would like for this guide to address questions such as. Do I resolve the suggestions directly on with the GitHub UI or through my local Gatsby setup? How to solve multiple suggestions at once using the GitHub UI, how to follow up with discussions, etc.

There's already a section on the How to Open a Pull Request guide on how to keep your fork updated, and I think this guide could either point out to that section or place that content in it.

If it's something you consider useful I could work on it.

Hey @urielhdz! That sounds like great information to include. I'd recommend putting it in the existing How To Open a PR doc rather than a separate one since it's the same workflow – you'd have to first open a PR to the information to be relevant. What do you think?

Closed with #18745. Thanks @urielhdz!
