In #1514, we added a symlink so that the docs would show up on the demo app …but symlinks aren't supported on Windows and was causing a problem when trying to bundle.
This instead adds a lookup table of files not in docs/ which allows us to render those.
This partially fixes #1693 (closed), in allowing Administrate itself to be bundled without a symlink but other dependencies have the same problem.
