d/rules: fix javadoc generation (Closes: #1108567):
This MR addresses #1108567.
Java 25 changes location of JQuery and JQuery UI css and script files. To maintain compatibility with Java 21 and future Java versions I have used find to locate necessary files. Javadoc uses a versioned JQuery, so I have replaced links to use a generic jquery.min.js.
Testing:
- rebuild in sid chroot
- installed documentation package and browsed documentation, no javascript errors
- rebuild in sid chroot with default Java 25
- installed documentation package and browsed documentation, no javascript errors
