Most AdoptOpenJDK references and API calls should swap to Adoptium

As per the [Blog Post in 2021](https://blog.adoptopenjdk.net/2021/08/goodbye-adoptopenjdk-hello-adoptium/) - AdoptOpenJDK has migrated to the Eclipse Foundation and serves binaries through adoptium.net.

**NOTE:** This is not a straight simple swap as some legacy/old Java binaries are only made available through the old AdoptOpenJDK API which setup-java may still wish to support.
