[PATCH 2/2] docs: Add redirects configuration for gitlab pages

[Peter Krempa]

Adapt the configuration of redirects from the server hosting libvirt.org

The redirect to the 'libvirt-console-proxy' Golang module is not adapted
as it doesn't exist on the current server.

NOTES:
 - The redirects are currently configured for hosting via the
   'gitlab.io/libvirt' URI. For hosting via custom domain it will need
   to be rewritten to drop the '/libvirt' prefixes.

 - gitlab pages doesn't currently support redirects to outside content,
   thus most of the redirects don't actually work:

     https://gitlab.com/gitlab-org/gitlab-pages/-/issues/601

 - The redirects file is only installed in the webpage job but is not
   actually distributed.
