Automatically hide rule list column when splitting the rule list by it

[bmish]

eslint-plugin-jest splits their rule list by meta.docs.requiresTypeChecking, but then has to manually list out all the rule list columns minus the "requires type checking" column to avoid showing it unnecessarily. We could do this automatically.

https://github.com/jest-community/eslint-plugin-jest/blob/7984bc211cad0a8e226202a2ebf241956169c064/.eslint-doc-generatorrc.js#L9-L19

My only concern is that this "magic" would preclude someone from including the column if they for some reason still wanted it in this situation (despite it being redundant).
