/*
Redefine these types for these reasons:
1) We can better control what properties are option and what are not.
2) We have to replace definitions with our definitions which use our typescript-estree types.
3) We can better document the fields so it's easier for new contributers to understand.

The def is wrapped up in a fake module so that it can be used in eslint-rules.d.ts
