Possible regression with custom domains and localized paths

Environment

Operating System: Darwin
Node Version: v20.15.0
Nuxt Version: 3.12.4
CLI Version: 3.12.0
Nitro Version: 2.9.7
Package Manager: bun@1.1.22

Reproduction

https://github.com/darioielardi/nuxt-i18n-play

On main you'll find @nuxtjs/i18n@^8.3.3 installed. To test with @nuxtjs/i18n@8.2.0 switch to the nuxt-i18n-v8.2 branch.

To test different domains you need to add this to your hosts file:

0.0.0.0 nuxt-i18n-play.en
0.0.0.0 nuxt-i18n-play.it
0.0.0.0 nuxt-i18n-play.fr

Describe the bug

My use case is an application with a different domain for each locale, and localized paths. For example:

my-website.com/travels
my-website.it/viaggi
my-website.fr/voyages

Until v8.2.0, I would set differentDomains: true, set up the locales with relative domains, add localized paths with customRoutes: 'config' + pages config, and it worked perfectly.

From this PR (as someone noted in the comment) that doesn't work anymore, as it will add a locale prefix to every path, which is of course redundant and undesired in my case.

Adding strategy: 'no_prefix' doesn't work with custom paths (as it's stated in the docs), but in the case of different domains I think it's reasonable to expect that the prefix is omitted anyway (as it was in v8.2.0), or at least to have some way to configure that.

Is the new behavior unexpected (and therefore a bug) or I'm missing something? Let me know if you need any more context, and thanks for your great work!
