stirling-pdf: Create a `stirling-pdf.bat` run it with window instead of run in background

[scillidan]

Mainly refers to languagetool-java.json, which create a languagetool-java.bat to start up as a background service (although I recommend using servy to manage services.

And stirling-pdf.jar is "front-end UI + back-end service", so I think it's better not to hide the command window and use java instead of javaw.
