fix matching of package versions on debian, ubuntu, and raspbian

[thaJeztah]

• relates to [master] deb: move packaging revision before distro information docker-ce-packaging#818

The version-format of the packages changed in the docker-ce-packaging repo; docker/docker-ce-packaging@39772a7

Which caused the script to fail when specifying a version:

INFO: Searching repository for VERSION '23.0.0-rc.2'
INFO: apt-cache madison 'docker-ce' | grep '23.0.0.*rc.2.*-0~debian' | head -1 | awk '{$1=$1};1' | cut -d' ' -f 3

ERROR: '23.0.0-rc.2' not found amongst apt-cache madison results

Looking at that search, it seemed like it was overly strict;

• matching the distro (debian, ubuntu, or raspbian), which should not be needed, assuming the package repository has been set up correctly (which the script does in earlier steps).
• matching the "0" prefix, which was intended to be used a package-revision (so to allow for packaging-only releases). That part definitely shouldn't be done, as it would not match later revisions (1, 2, 3)

This patch simplifies the matching, and only searches for the package name, and the version specified, which should satisfy the requirement;

apt-cache madison 'docker-ce' | grep '23.0.0.*rc.2' | head -1 | awk '{$1=$1};1' | cut -d' ' -f 3
5:23.0.0~rc.2-1~ubuntu.22.04~jammy

apt-cache madison 'docker-ce-cli' | grep '23.0.0.*rc.2' | head -1 | awk '{$1=$1};1' | cut -d' ' -f 3
5:23.0.0~rc.2-1~ubuntu.22.04~jammy

With this patch applied, the installation succeeds:

cat install.sh | DOWNLOAD_URL=https://download-stage.docker.com CHANNEL=test VERSION=23.0.0-rc.2 REPO_FILE=docker-ce-staging.repo sh
