packaging: stop installing Contributors.txt
This file isn't up to date. If we are going to call out
contributors, we should auto generate a file from `hg log`
or something. I don't think we need to include it in the
Windows install.
This change makes Inno more consistent with WiX, which
doesn't ship this file.
