Auto merge of #13748 - epage:kebab, r=weihanglo

refactor(config): Consistently use kebab-case

This shouldn't change the behavior but makes it safer if
- We add new fields where it will matter
- Copy/paste these for new structs

I did not change things related to the Index because we are already stuck with that case (whether we want it or not)

Came across this when working on #13540 and almost made the mistake of copying what was already there
