Use version 4.2.3 on Dockerfile

[devaughnsaxa]

I can see that the kscript version 4.2.3 is missing on the Dockerfile https://github.com/kscripting/kscript/blob/master/misc/Dockerfile.

This makes it unable to run scripts with modules written in Kotlin with newer versions.
I get this error (shortened for brevity)

... [kscript] [ERROR] Stderr : 'error: incompatible classes were found in dependencies.

Is that something you could fix? I would really appreciate that.
Thanks in advance and have a nice day :)
