Update to eclipse-temurin:21 and remove appuser (#4675)

It seems this appuser wasn't being used at all, and the USER line wasn't being set to enable it. In addition, the adduser utility didn't exist in the old or updated version of temurin. This seems simpler and works. Signed-off-by: James <[email protected]>
