This resolves a Service360 alert caused by Ubuntu refusing to make a
security patch publicly available for Ubuntu 22.04 LTS, see
https://ubuntu.com/security/notices/USN-6472-1 .
It seems likely that we will need to reconsider Ubuntu being our
'default' test environment following this type of behavior, since it's
likely vcpkg customers will be similarly affected.
