"Add to an organization" in the team settings opens a modal but was an
<a> without href: the keyboard could not reach it. It is now a
<button type="button"> that keeps its text-link look (accent color,
medium weight, underline on hover, the same box), so Tab reaches it and
Enter or Space opens the modal.
New visual test "Shows the Add to an organization link", with fixtures
for a team in no organization and an organization the user belongs to:
0 px of difference at rest and on hover, and 0 px on the whole settings
page.
