The MongoDB 8.0 apt repository configuration for Ubuntu 24.04 downloads
the GPG key into /usr/share/keyrings/mongodb-server-8.0.gpg but the deb
source line does not reference it via signed-by. On standard Ubuntu
24.04 systems, apt treats unsigned repositories as a hard error, causing
stack.sh to fail with exit code 100.
Add signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg to the deb
line in both devstack/plugin.sh and tools/test-setup.sh, matching the
pattern already used for Debian 12/13 in test-setup.sh.
