Paraglide-Next Static Export

[LorisSigrist]

Context

paraglide-next currently doesn't work with static export.

Blockers:

• Uses middleware for language detection & rewrites -> Not supported
• Uses headers to manage language state on the server -> Not supported
• Doesn't have a [locale] parameter, so pages can't be rendered multiple times (very silly limitation from NextJS)

Proposal

Add a way to bypass the blockers if static export is desired

• Allow using a [locale] parameter for rendering multiple pages
• Use the [locale] parameter for server-side language state. We can use react's use hook to scope the state to the request -> No crosstalk
• Add a way to generate <link rel="alternate"> links instead of using the Link header
• Add Documentation

Static export is the exceptional case, but people expect support for it.
