jruby vs jdk updates

jruby has a file containing the jdk version. whenever the jdk/21 minor
version changes, jruby no longer packages. I fixed this up a couple of
times recently but I wonder if there's a better way of handling this.

At least there should be a comment in jdk/21.

Here's what I just committed:
