[BUG] Plugin doesn't support nuxt layers

[GMartigny]

Describe the bug
I have a bunch of shared configuration stored in a layer that my projects inherit from. In this shared layer, you'll find the tailwind config file with some custom colors (or whatever). Unfortunately, the plugin doesn't seems to be able to get the config from the layer.

To Reproduce

• go to the minimal reproduction repo
• run ./prepare.sh
• run npm run lint
• See that an error is raised

Expected behavior
As the color exists in the layer, it shouldn't raised an error. You should note that the error is not thrown when running eslint inside the shared layer, as the color is correctly detected.
