* Prefer maven URLs going forward

  We continue to maintain the S3 URLs but only as a courtesy for
  legacy apps and tools. The preferred URLs are the maven jruby-dist
  links, which have the same files but are federated and mirrored
  across the maven ecosystem.

* Add JRuby 9.3.1.0

* Add TruffleRuby and TruffleRuby GraalVM 21.3.0

ruby-build 20210928

* Fix version check for Java 17

  * Fixes rbenv#1798
  * OpenJDK 17 reports:
    $ java -version
    openjdk version "17" 2021-09-14
    There is no dot in the version, so we need to only use the first match from grep -o.
  * Clarify it is a minimum required java version, not an exact version.
