Try to parse java.version from pom.xml

[c0d1ngm0nk3y]

see #217

Summary

If a pom.xml is found, it is parsed and checked for the java.version property (spring boot). If the property is found, this information is used to not only require a JDK, but a JDK of the correct version.

Use Cases

If a spring boot application is requiring a specific java version (e.g. 17) which is different from the default one being installed, the user is not forced to provide BP_JVM_VERSION , but the version is auto detected.

Note: This would need a change for libjvm to honor the required metadata.
