feat: Internationalization

[FleetAdmiralJakob]

Describe the feature you'd like to request

Would be cool if there is internationalization in this repo. So you can start out of the box with good internationalization.

Describe the solution you'd like to see

Maybe use the solution from: https://nextjs.org/docs/app/building-your-application/routing/internationalization, but I'm not a big fan of this solution so idk.

I would also like to see an i18n function. There is the next-intl project.

Here is an inspiring demo:

I think internationalised pathnames are a bit overkill as a lot of maintenance is required, so example-app-router-minimal should be perfectly fine.
