Mini patterns: Examples of component compositions

[mrosvik]

We want to create dedicated examples that demonstrate how multiple components can be combined in practical scenarios. This will help users of Designsystemet understand how components work in context, not only as standalone elements.

A good reference is how Udir has done it here: Udir example page

These examples correspond to what is often called organisms in atomic design, larger building blocks made up of multiple components that work together in a meaningful way.

Examples:

• Table with multiple components inside and outside
• Phone number with country code combined
• Addresses, different structures in Norway vs. international contexts

After #3966 we can implement this directly in www
