QA not using the script but the bash commands.

➜  cli git:(fix/1183/fix-install-script) old_version=$(scalingo --version | cut -d' ' -f3)
➜  cli git:(fix/1183/fix-install-script) ✗ echo $old_version                                
1.43.0

cut -d' ' -f3 is still quite brittle because it assumes the version will always be the 3rd whitespace-delimited token. Since --version output formatting can change (extra words, different binary name, etc.), consider extracting the last token instead (e.g., via awk '{print $NF}') or a simple semver regex, to make version detection more robust.
