JVM version output can omit minor or patch suffixes

[MattAlp]

What Does This Do

Patches the setup script to account for release numbers with minor / patch omitted.

Motivation

The ./setup.sh script presumes that the version number output of java -version will follow semver conventions, so major versions will be followed by a .. In the case of some JDKs, i.e. Temurin 17, the output only includes the major number:

dd-trace-java % $JAVA_17_HOME/bin/java -version                                
openjdk version "17" 2021-09-14
OpenJDK Runtime Environment Temurin-17+35 (build 17+35)
OpenJDK 64-Bit Server VM Temurin-17+35 (build 17+35, mixed mode)
