CI failing because tarballs aren't available anymore
Gitlab CI is failing now because the tarballs aren't available anymore. See https://gitlab.common-lisp.net/cmucl/cmucl/-/pipelines/6045. For example, we want to get https://common-lisp.net/project/cmucl/downloads/snapshots/2021/07/cmucl-2021-07-x86-linux.tar.bz2, but that returns a 403 code (forbidden).
This is probably due to the recent change in site generation, and I don't know what the correct path is now.
