Revert #10591: use sbt-jmh 0.3.2

  • sbt-jmh 0.3.2 uses jmh 1.19
  • sbt-jmh 0.4.0 uses jmh 1.25

Run the same command:

scala3-bench-bootstrapped/jmh:run tests/bench/FindRef.scala

sbt-jmh 0.3.2 takes <1 min, while 0.4.0 takes ~8min.

Not much information found in the archive and internet:
https://mail.openjdk.java.net/pipermail/jmh-dev/

Will eventually update when we have a better fix.
