Ruby version changes

3.0
- GC.auto_compact= and GC.auto_compact have been added to control when compaction runs. Setting auto_compact= to true will cause compaction to occur during major collections. At the moment, compaction adds significant overhead to major collections, so please test first! [Feature #17176]
