Linting all things in IDE - the ultimate doc

[zzap]

This has been proposed as developer docs page but I think it fits better into dev blog, due to the nature of development tools and workflows to change without affecting the actual development.

This is the original issue: WordPress/Documentation-Issue-Tracker#34

A comment from @jrfnl:

I wonder if there should be multiple articles for different target groups ?

How to set things up & get it running locally for contributing to WP Core
Best practices for setting things up for a plugin/theme and how to integrate it into CI
How to set up your local tooling environment in general (project vs global, IDEs etc)
