version-selection fails if the version matches the distro version

This was a fun one I ran into this when trying to install an old version of docker for testing. The machine I ran this on was an ubuntu 24.04 "noble" machine; when I tried to install Docker 24.0, it matched the 24.04 version in the packages, resulting it to install the latest version (docker 28.4.0);

curl -fsSL get.docker.com | VERSION=24.0 sh
# Executing docker install script, commit: 30c930eeebfc0bdf50564bcda65e90588b35ec2a

Start with the installer entry point invoked by get.docker.com and inspect the apt-cache madison filtering shown in the report. Reproduce VERSION=24.0 on Ubuntu 24.04, then verify that the selected package versions correspond to Docker 24.0 rather than the distro version 28.4.0.
