Original prompt

Upgrade nuxt and all of it's related dependencies. Ensure all modules are updated to the last version. Ensure that the nuxt eslint module is used, and updated all related dependencies there including prettier. Drop the google fonts module in favour of nuxt/fonts, and use Bunny as the provider for any fonts currently being used.
