AirBnb only imports JavaScript rules and some fail for TypeScript files. This commit overrides those rules with TypeScript equivalents. Changes here can be mostly replaced when Vue natively support TypeScript for Airbnb (vuejs/eslint-config-airbnb#23). Enables @typescript-eslint/indent even though it's broken and it will not be fixed typescript-eslint/typescript-eslint#1824 until prettifier is used, because it is still useful. Change broken rules with TypeScript variants: - `no-useless-constructor` eslint/eslint#14118 typescript-eslint/typescript-eslint#873 - `no-shadow` eslint/eslint#13044 typescript-eslint/typescript-eslint#2483 typescript-eslint/typescript-eslint#325 typescript-eslint/typescript-eslint#2552 typescript-eslint/typescript-eslint#2484 typescript-eslint/typescript-eslint#2466
