Build out a prototype of an updated Contact Us form

[h-m-f-t]

Issue description

In #288, we experimented with modifying the Contact Us form to guide users to the right answers so (perhaps) they don't need to submit the form at all. In this issue, let's build a working prototype of the form and solicit more feedback from the team on whether the approach is viable.

Acceptance criteria

• Using the FAQs as a guide, build a prototype of a new form using the approach started in the duplicate contact us form (if needed, ask @h-m-f-t to be added as a collaborator on the form).
• Present an MVP for feedback to @cisagov/gov-designers (needn't account for every permutation but should be functional for several common questions)
• As a team, decide go/no go. If go, create an implementation issue

Additional context

#288 talked about exploring the sending of emails upon submission. We didn't explore that, but that could also be part of the final implementation.
