fix: Forms - Add 'escape' button / key handler in forms (#240)

In v1, we had a quick and easy way to leave creation forms - an escape button (and key handler) in the top right corner.

This was especially helpful in cases where the form was long enough that the 'Cancel' button was off-screen.

This ports over that component into v2 and hooks up into our two existing forms:

In addition, this adds test cases + a storybook story for it.
