[jsscripting] Fix regressions from #14135 & Log stack on `IllegalArgumentException` (#14142)

* [jsscripting] Fix bundling of global script & regression from #14135

Fixes the regression from https://github.com/openhab/openhab-addons/pull/14135#issuecomment-1369231126.

While working on this, I also noticed that the cache openhab-js does not work because of wrong webpack commandline args in the pom (wrong entrypoint).

* [jsscripting] Enable stack logging for IllegalArgumentExceptions
* [jsscripting] Upgrade openhab-js to 3.2.4
* [jsscripting] Update README for recent PR
