Documentation for each component

### Component documentation
We currently have no structured information about the capabilities of our components in the user docs. We have the technical docs in our json-schema, but more visual and descriptive docs would be useful.

I feel it would be natural to also structure the component guidelines (https://docs.altinn.studio/app/design/guidelines/components/) together with a technical overview of what is possible with the component to enable app developers to take full advantage of the capabilities.

## Tasks
- [ ] Setup docs for each component with a technical documentation how a component can be used
- [ ] Combine (or at least link to) guidelines for how to use them

Ideally, these docs should be placed under `Create apps \ Development \ User Interface ` in a dedicated component section.

Start by reviewing the existing technical information in the json-schema and the component guidelines at docs.altinn.studio/app/design/guidelines/components/. Identify the components and documentation structure under Create apps > Development > User Interface. Done means each component has visual, descriptive, and technical usage documentation, with its guidelines combined or linked.
