feat: Multi sitemaps with i18n

[ronenteva]

🆒 Your use case

When using both multi sitemaps and i18n, it will be useful to still have a separate sitemap for each language.

nitro.config.js:

sitemap: {
    sitemaps: {
      shirts: {
        sources: ['/api/sitemap/shirts']
      }
    }
  }

/api/sitemap/shirts:

export default defineSitemapEventHandler(async () => {
  return [{
    loc: `/shirts/white`,
    _i18nTransform: true
  }];
});

This will generate /__sitemap__/shirts.xml which contains pages in all languages.

🆕 The solution you'd like

/__sitemap__/shirts/en.xml
/__sitemap__/shirts/es.xml
...

Google does not support nesting multiple index sitemaps within each other so this is not something I will implement, sorry.

[ronenteva]

Oh right, sorry about that. What about /__sitemap__/shirts-en.xml?

[harlan-zw]

It's possible but it's unlikely I'll attempt this any time soon as there's quite a bit of complixity involved in supporting this.
