docs(SelectPanel): update docs with keyboard interactions

[joshblack]

This PR updates the docs for SelectPanel to document the keyboard behaviors supported by the component. It also adds in an initial Status section and initial Props.

Questions

• Is the interaction guidance here appropriate? I wasn't sure if keyboard interaction docs should live here or somewhere else 👀
• What's the best way to write out the props for SelectPanel using the existing MDX components?
• Is the ComponentChecklist correct?
