Share motivation/rational for each rule

[lwouis]

Hi,

Thank you for this great project!

I ran it on our project in linter mode. The first error I got was preferForLoop. I thought that it's interesting that SwiftFormat considers that it's a bad practice to use forEach, and recommands using a for loop instead. However, I was left a bit curious as to why forEach is a bad practice.

I looked around in discussions on this project, but couldn't find a place where the motivation/rational beyind each rule is.

What would you think about adding this extra piece of information? I think it could help developers to know why a pattern is to be avoided, in addition to pointing it out.

Thank you 🙇‍♂️

for in is more controllable, but equal in performance measurement
