Panel component should accept data-id prop

[nicklemmon]

🚀 Feature request

Current Behavior

<Panel data-id="something"/> does not currently render to the DOM.

Desired Behavior

Ideally, passing a value via data-id would render to the outer Panel element, allowing for chunking of sections of a page in Cypress.

Suggested Solution

Make sure this prop is being passed for nearly all components in Matchbox.

Who does this impact? Who is this for?

FE engineers for testing, product folks when it comes to targeting elements via Segment and other tools.
