They omit the Java version and have `-dev` earlier for consistency with other artifacts.
Example:
- old: `graalvm-community-java26-linux-amd64-dev.tar.gz`
- new: `graalvm-community-dev-linux-amd64.tar.gz`
This commit adds support for the new GraalVM for JDK17/JDK20 release, including the new Oracle GraalVM distribution.
For this, users only need to specify the 'java-version' option and the new 'distribution' option.
The 'version' option is now marked as optional and kept for compatibility with older GraalVM releases and Mandrel.
