Conversation
…tible with Ruby 4 **What does this PR do?** Update profiler docs to reflect the fact that heap live size profiling is currently not compatible with Ruby 4, as per PROF-15376 JIRA and DataDog/dd-trace-rb#6022 . (Heap live objects profiling is unaffected.) I did spot that vale doesn't like the word "currently" yet I believe that's the most accurate representation of the state here -- we've had to disable the feature due to bugs, but we do intent to restore it in the future.
