[CentOS-docs] CentOS 4.7 Release Notes on the wiki not mentioned in the announcement

[Akemi Yagi]

It was unfortunate that the CentOS 4.7 release announcement did not
refer to the Release Notes on the wiki:

http://wiki.centos.org/Manuals/ReleaseNotes/CentOS4.7

I propose to put this link in the Download page (
http://wiki.centos.org/Download ) instead of, or in addition to, the
current link which points to the 4.7 announcement.
