Bug#1040675: ca-certificates-java: incorrect "Breaks:" versions about ubuntu

[Matthias Klose]

Control: severity -1 important

openjdk-18 has been removed from testing in November 2022, and I now filed a bug 
report to remove it from unstable (#1040789). It is unmaintained upstream, and 
superseded by newer OpenJDK releases.

The versions used in these breaks work both for Debian and Ubuntu. If there are 
mistakes made, please tell them. Shouting "this is Debian" doesn't help.

I'll close this issue once openjdk-18 is also removed from unstable.
