This issue is automatically created based on existing pull request: magento/pwa-studio#3648: Fix typo in component import name; consolidate import

Verification Steps

1. Navigate to a category.
2. Make sure "Add to Cart" button exists.
3. Click "Add to Cart" button.

Description

This fixes two nitpicks:

• The button in the import was inconsistent with both the file name and component.
• Going up to the parent directory and back down is inconsistent and unnecessary.

Test Execution -

1. Run cypress and make sure build passes.
