i18n, autogenerate: support different set of documents per locale

[siddie]

What version of starlight are you using?

0.30.3

What is your idea?

It would be great if Starlight in autogeneration mode supported different set of documents per locale.
Here is the file structure, that contains different set of articles for different languages:

*content
*--docs
*----en
*------start-page.mdx
*------wiki
*--------slug-article-en-1.md
*--------slug-article-en-2.md
*----de
*------start-page.mdx
*------wiki
*--------slug-article-de-1.md
*----fr
*------start-page.mdx
*------wiki
*--------slug-article-fr-1.md
*--------slug-article-fr-2.md

What I see now:

1. There is a hard constraint to always define the default locale. When setting up autogenerate from 'wiki', having 'en' locale as default, in the build I get the the default locale articles mixed into the other locales content:

`
en/wiki/slug-article-en-1.
en/wiki/slug-article-en-2

de/wiki/slug-article-de-1
de/wiki/slug-article-en-1
de/wiki/slug-article-en-2

fr/wiki/slug-article-fr-1
fr/wiki/slug-article-fr-2
fr/wiki/slug-article-en-1
fr/wiki/slug-article-en-2
`

Those pages are visible on the Sidebar, in the build, in the sitemap.xml.

Ideally, the default locale pages should not be duplicated into the other locales.

2. Since the article sets are different, when being on the DE locale https://example.com/de/wiki/slug-article-de-1 and switching to the FR locale via the language picker, I get a 404, since current behaviour is to show https://example.com/fr/wiki/slug-article-de-1

It woul be nice if in this case I was redirected to some default page of my wiki, say, start-page.mdx

Does it make sense?

PS: I am currently achieving the (1) via quite a hacky approach. Have not yet solved the (2).

Why is this feature necessary?

It is quite common for the knowledge base sites to provide different content for different languages, in other words, extending from internationalization to localization.

Do you have examples of this feature in other projects?
