docker: updates zipkin-cassandra test image to 4.1.8

If you just update to 4.1.8 and change nothing else, you'll crash like this:

This is due ultimately to needing to upgrade jamm, which had some signature drift. CASSANDRA-18329 fixes this in 5.0, but not in 4.1.

CASSANDRA-18329 fixed this particularly by updating call sites to jamm in ObjectSizes.java.

We use JRE 21 in our test image even though cassandra 4.1 doesn't really support it, to save base layers. The easiest way to fix this was to grab the ObjectSizes.java file from 5.0.3 and the revert their renaming of a public method so it could be a drop in patch.

this works as some time in the past we were already adding classes. So, "classes" is already in the run scripts else startup would fail.

security fail will resolve with #3793

@reta mind merging this one, too prior to release after any polishing you might want to do?
