[Nuxt] Change nuxt.hook usage to Vite `config` hook

[s1gr1d]

The Nuxt lifecycle hook vite:extendConfig is deprecated (we are currently using this one in the repo).

Instead, config from Vite should be used:

If you're writing code that needs to access resolved Vite configuration, you should use the config and configResolved hooks within your Vite plugin, rather than using Nuxt's vite:extend, vite:extendConfig and vite:configResolved.
