CentOS 8 Stream already reached its EOL. AFAIK it was already removed from
the source mirror and is no longer available. You should use CentOS Stream 9
or other distributions like Rocky or Alma.

Also please be aware that the TripleO project has already been retired and
is no longer maintained. I'd also suggest using a different deployment tool
(like openstack-ansible, kolla or puppet-openstack, for example).
