It shouldn’t try to download any Jetty related files at all. If the upgrade to 3.3.0.M5 went succesful, it should have all the Jetty 9.4.46.v20220331 files pre-installed in /usr/share/openhab/runtime/system/org/eclipse/jetty and use those. So it seems the update didn’t go well and it thinks it should get those older Jetty libraries. Maybe you can restore a backup and try updating again?
