I assume 4.0 is the recommended version? If so, bump GHA check to pick up 4.0.

@shipilev Thank you for the review, I updated GHA workflow to use async-profiler 4.0. Changes are compatible with all profiler versions. If user specifies an option specific to 4.0 while running and earlier profiler version, JMH will not check it by itself, but an exception will be thrown directly from libasyncProfiler, which I think is expected behavior.
