[Script request] Update openHAB LXC to use zulu21-jdk

Description

openHAB 4.3.x (current version) requires java17 or java21. openHAB 5.x, due to be available in 5 months, requires java21.

Upgrading the java version has no effect on production systems, but will allow openHAB 5.x testing

Due Diligence

• I have searched existing scripts and found no duplicates.
• I have searched existing discussions and found no duplicate requests.
• This is not a game-related request.

The Openhab recommendation is, to use Java 17 for Openhab 4.x and Java 21 for Openhab 5.x.
I have some problems with some bindings with Openhab 4.3.5 with Java 21 and ask to adjust the script to select the Java version 17/21 in the "Avanced Settings" configuration ... or have two different scripts one with Java 21 and one with Java 17.

This is the Openhab warning for 4.3.x!
