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

首先阅读 update.sh，重点关注如何解析 -s MAJOR_VERSION 参数并将其与可用版本进行匹配。运行 ./update.sh -s 26 以复现当前行为，然后验证不受支持的版本（如 23 或 26）会因错误而失败，而受支持的版本则继续正常更新。

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
