Would be nice to be able to use regex literals to not have to double-escape certain characters when using JS-based ESLint config.

Before

'@typescript-eslint/generic-type-naming':['error','^[A-Z][a-zA-Z\\d]+$'],

After

'@typescript-eslint/generic-type-naming':['error',/^[A-Z][a-zA-Z\d]+$/],

It also means it becomes syntax highlighted and ESLint (through some built-in rules) can prevent some common mistakes when you lint the config itself.

This would require changes to the following rules:

• @typescript-eslint/generic-type-naming
• @typescript-eslint/member-naming
• @typescript-eslint/no-unused-vars
