📚 Description

• Resolves Allow defining baseUrl via runtimeConfig #1908

Allows us to set the baseUrl via runtimeConfig as follows:

export default defineNuxtConfig({
  runtimeConfig: {
    public: {
      i18n: {
        baseUrl: 'https://example.com',
      },
    },
  },
})

This way the baseUrl can be overwritten by setting the NUXT_PUBLIC_I18N_BASE_URL environment variable, which makes it easier to deploy from development, to staging and production environments without rebuilding or making changes to code.

I added some debug logs for easier debugging which configuration is being used to set the baseUrl.

The current implementation works by settings public.i18n.baseUrl, if there is a preference to have it in the secret/private runtimeConfig instead I can change it accordingly. Because of this I haven't added documentation to this PR yet.

There may be other configurations we could also add runtimeConfig support for, I'll keep that in mind when adding documentation if this feature gets approved.

@kazupon I have added documentation for the functionality, I tried to keep it generic in case other options will support setting through runtimeConfig in the future.
