Expand upon current IDE setup instructions

[timtebeek]

We already have a few places where we describe how to best tune your local environment and IDE for recipe development:

• https://github.com/openrewrite/rewrite/blob/main/CONTRIBUTING.md
• https://docs.openrewrite.org/authoring-recipes/recipe-development-environment
• https://docs.openrewrite.org/reference/building-openrewrite-from-source

Yet we can possibly do more to lower the barrier for entry into development. Two questions that came up on my end for instance:

1. When I execute the tests, there is a noticeable delay before the tests start executing, possibly related to resolving latest.release dependencies. What can be done (and documented) to prevent that?
2. When a recipe does not produce the expected diff, the expected and actual values are printed to the console by default. How to open a dialog for easier visual comparison?

Possibly there will be more such questions for people just getting started, and it would be good to ensure those are resolved to create a smooth recipe development experience.

Could be worth documenting the toggle to Run tests using: IntelliJ rather than Gradle for both a speed up and easier result comparison.
