SLING-7437 - Support Jackrabbit 2.16 in org.apache.sling.jcr.registration

Update to changes added in JCR-4195. Rather than keeping a large version
range, I chose to pick a new dependency version. This being related to
RMI and:

a) less often used
b) not easy to test

I prefer the safe side of increasing the dependency.
