Dead links on developer.gnustep.org

[Denislav08]

Hello, I have noticed a few dead links in the GNUStep documentation.
The one in https://developer.gnustep.org/About/Contributing/index.html
instead of https://mail.gnu.org/mailman/listinfo/discuss-gnustep
it should be https://lists.gnu.org/mailman/listinfo/discuss-gnustep.
in https://developer.gnustep.org/Guides/App/1_Intro/index.html
On the base category, all the links are dead too.
Thanks :).
