Add tooltips for labels (#665)

We already have a list of label definitions but don't display them. I
think showing the definitions could clear up a bit of ambiguity (does
"hardware" mean "runs on hardware", or "for designing hardware"?)

This PR uses the carbon tooltip component to display these on the
website.
