Eslint should ignore parent .eslintrc configuration

[hsingyuc]

Describe the bug

Eslint uses both the parent and the current repo's eslint config file.

Similiar issue woocommerce/woocommerce-gateway-stripe#2413

To reproduce

1. Create a woopay docker instance
2. Clone the woocommerce-blocks plugin to woopay/docker/wordpress/wp-content/plugins/woocommerce-blocks
3. Run npx eslint --debug .eslintrc.js to see eslint is using the config file from woopay

Expected behavior

woocommerce-blocks should use its own eslint config file
