UI Component Library for Altinn Studio UI Designer

### Description

We need a better component catalog for Altinn Studio UI Designer that show the user everything about the components

### Additional Information

- What it looks like
- How it should be used

- [ ] Update documentation for all components with the new template

### Acceptance Criterias

## Update component docs
For components that have documentation, this must be updated with the new template.
The template files are located in `components/temp/components-to-update` with a folder for each component.

#### To update a component, do the following:
1. Rename the component's current folder (or move to temporary location).
2. Move the component's new folder with templates from `components/temp/components-to-update` into the `components` folder.
3. Copy content from the old docs to the new template and fill in any missing sections (follow the instructions in the template). If the new folder name differs from the old one, add an alias with the old name.
4. Delete the old folder
