Integrate a locale switch

[tboerger]

We need to add a locale switcher if there are translations available. Maybe we should also integrate an automated redirect based on https://caddyserver.com/docs/locale and https://caddyserver.com/docs/redir.

Currently we got a locale switch in the footer of the theme, but on the long term we want to detect the locale automatically as mentioned above.

So which milestone to do that?

The docs are not based on milestones yet, maybe i can give it next week a shot.

If your browser provides a matching accepted language it's redirecting there, otherwise it got a fallback to en-US
