fix: derive JAVA_FULL_VERSION from the real OpenJDK version, not the Zulu build number

The java.version format changed to Azul's CDN filename style (e.g.
zulu11.92.109-ca-jdk11.0.33), which broke the cut-based parsing: it
produced tags like hypertrace/java:zulu11 and
hypertrace/java:zulu11.92.109 instead of updating hypertrace/java:11,
and JAVA_FULL_VERSION no longer matched the actual OpenJDK patch
version consumers expect (e.g. 11.0.33).
