kernelci-frontend-config missing from wiki/downloads

Robert Marshall <robert.marshall@...>

In the 0.9.1 release the kernelci-frontend-config archive has been
missed from the download page for the sources, this has now been
rectified. It was also missing from the features page and this is in
the process of amendment.

Apologies to anyone who downloaded all the sources thinking they had the
complete set, you will need to revisit
and download the extra file and its associated checksum and gpg sig.

We will also add kernelci-frontend-config to our list of mirrored git
repos but need to sort out
administration for this.
