add javadoc subpackages

[judovana]

Fedora rpms have java-xyz-openjdk-javadoc and java-xyz-openjdk-javadoc-zip suboakcages.
While readning #814 ; I realised temurin rpms do not have this
The java-xyz-openjdk-javadoc-zip ( which contains still the same javadoc, only in zip) exists next to plain java-xyz-openjdk-javadoc, because a zip with docs is much more easily indexable by IDEs

This will be currently lost with migration to temurin jdk, but it is very minor I think.
