`update.sh` updates all versions for non-matching version input

Environment

• Platform: Ubuntu 24.04.4 LTS
• Docker Version: N/A
• Node.js Version: 24.14.1
• Image Tag: N/A

Expected Behavior

If the update.sh script is run using a MAJOR_VERSION that is not set up, such as 23 (EOL) or 26 (not yet released), the script should fail with an error message.

Current Behavior

The script acts as though no MAJOR_VERSION was specified and updates all available versions.

Possible Solution

Steps to Reproduce

Execute:

./update.sh -s 26

Lies zunächst update.sh und konzentriere dich darauf, wie das Argument -s MAJOR_VERSION geparst und mit den verfügbaren Versionen abgeglichen wird. Führe ./update.sh -s 26 aus, um das aktuelle Verhalten zu reproduzieren, und überprüfe anschließend, dass nicht unterstützte Versionen wie 23 oder 26 mit einem Fehler abbrechen, während unterstützte Versionen weiterhin normal aktualisiert werden.
