Java 8 support?

[jeremylong-snc]

It appears the latest release of cyclonedx-core-java was compiled with JDK 17.0. The cyclonedx-gradle-plugin is still setup to support Java 8.0 - and as such, an upgrade of the cyclonedx-core-java library causes build failures:

Caused by: java.lang.UnsupportedClassVersionError: org/cyclonedx/model/ExternalReference has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Any issue if we target JDK 8 still?

Java 8 is ancient at this point, and the change was made via #770 in accordance to community feedback.

The more reasonable way forward would be for the Gradle plugin to raise its baseline as well. Are there any major concerns with that?
