Bug 35504: Add full maintainers list into development branch

On a stable branch the current maintainer of your running version is
listed at the top of the current maintanence team.. however when you're
on a development branch the RM is responsible for your branch and the
maintainers were missing from display.

This patch adds the maintainers list back to the bottom of the current
maintanence team section, just for the development branch.
