Route intercept does not work with generateStaticParams in layout

[IikkaWinter]

Description

Route intercept seizes to work once generateStaticParams along with unstable_setRequestLocale are added to [locale]/layout.tsx. The params passed to the route group (modal) does not include locale.

NOTE: this does not manifest when running on local - only in prod mode.

Verifications

• I've verified that the problem I'm experiencing isn't covered in the docs.
• I've searched for similar, existing issues on GitHub and Stack Overflow.
• I've compared my app to a working example to look for differences.

Reproduction description

Steps to reproduce:

1. Clone my fork of nextagram-intl example repo
2. npm run build and npm start to start in prod mode
3. Open landing page and notice that the prefetched photo server components are responding with 404
4. Click on the picture and the photo root route is rendered instead of the modal
5. Observe the console log on server taking note on missing locale in modal params

Expected behaviour

The picture modal should be shown as when running in dev

Possibly related to #255, maybe also #663.
