Describe the feature

I’d like to configure my application so that a locale like pt-BR uses a human‑friendly prefix instead of the code in URLs.

E.g. /brazil/about instead of /pt-BR/about.

Ideally, something like this:

locales: [
  {
    code: 'pt-BR',
    file: 'pt-BR.yml',
    language: 'pt-BR',
    prefix: 'brazil'
  }
]

That way:

• I don’t need to map every route manually via pages config or macros.
• I can keep my existing locale code value (pt-BR) unchanged.
• I can support a custom prefix string (brazil) that’s meaningful and SEO‑friendly.

Additional information

• Would you be willing to help implement this feature?
