On ability pages, make it clear that there are more requirements beyond the progress bar

Prompted in part by https://meta.codidact.com/posts/291619.

If you haven't yet earned an ability, the page for that ability shows a progress bar. But that's only part of the story: there are also thresholds. The bar could show 100% because all of your (posts, flags, edits) are positive, and yet you don't have the ability because you needed more of them.

This interface is confusing, but because of how the sections of the page are separated in the code, I can't tell what it would take to show the thresholds next to the bar or change the bar to account for them. We could add some text saying "see additional requirements below", but that feels like a kludge. What can we do to make actual progress clearer here?
