verifyPackage.eslintImports don't detect .eslintrc.js conf

[stipsan]

When a .eslintrc is used the plugin-kit correctly detects that I have @sanity/no-v2-imports in my extends array.
But when using .eslintrc.js I get this error:

✖ 4 problems (3 errors, 1 warning)
ESLint detected Studio V2 imports that are no longer available.
It is recommended configure @sanity/eslint-config-no-v2-imports for ESLint.

Run:
npm install --save-dev @sanity/eslint-config-no-v2-imports

In .eslintrc add:
"extends": ["@sanity/no-v2-imports"]

This way, V2-imports can be identified directly in the IDE, or using eslint CLI.

If the plugin package does not use eslint, disable this check.

To skip this validation add the following to your package.json:
"sanityPlugin": {
   "verifyPackage": {
      "eslintImports": false
   }
}
