- Drops the Team page for privacy and accuracy. I don't want to pressure folks into feeling committed to the project through a page like this, and it also doesn't allow folks any privacy option (as you can hide org membership on your GitHub profile).
- Moves the History page into an Overview page, which includes an updated history page and a quick team blurb at the top.
- Added redirects to the new Overview page from Team and History
These were using `z-index: 2` to "Place active items above their
siblings for proper border styling". However, using `z-index: 1` is
sufficient for accomplishing that goal.
In input-group, there were also three `z-index: 3` rules for the
hover/focus/active states. I reduced these to `z-index: 2` since they
just needed to be "one more than normal" (i.e. one more than what is now
`z-index: 1` after my changes).
These changes can be verified by viewing the documentation pages for
Button group, Input group, List group, and Pagination before and after
this commit and observing that the active elements are still "above"
their siblings, so their borders look correct.
