cozy-harvest-lib lint does not handle ts files

[paultranvan]

When running yarn lint in cozy-harvest-lib dir, it does not include ts files: "lint": "cd .. && yarn eslint --ext js,jsx packages/cozy-harvest-lib".
And, when trying to add ts support, it fails with Error: Error while loading rule '@typescript-eslint/dot-notation': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser. .

This finally works when changing the .eslintrc file at the cozy-libs root:

{
   "root": true,                                                                                                                         
   "extends": "cozy-app/react",                                                                                                          
   "globals": {                                                                                                                          
     __DEV__: "readonly"                                                                                                                 
   },                                                                                                                                    
   "parserOptions": {                                                                                                                    
     "project": "tsconfig.json"                                                                                                          
   }
 }

But there might be a better way?
