Supported Java Versions

[ThomasVitale]

Continuing the discussion started in #511, let's talk about which Java versions this project officially supports.

We have already established a Java 17+ baseline.

Let's talk about whether we should support only LTS versions starting from Java 17, or if we also want to support the current version of Java (including whether we consider it supported or only for running tests to ensure everything works).

I'd say "support" is a tricky word 😄

Most OSS projects I work with generally only "support" the LTS versions. I don't think there's anything wrong with building and testing against the current interim version. I just don't think we can put a guarantee that if an issue arises it'll get fixed immediately. It'll get fixed sometime before the next LTS :)

I also don't think our checks against a non LTS build should block a PR from merging.
