Regexp.newaccepts any value asoptionswhile the doc says it acceptsInteger | nil | false. I found a code passingtrueand it cannot be rejected by a type checker, because the RDoc ofRegexp.newshows it as an example.This change will be reverted once Ruby 3.2 is out. The unexpected
optionsvalue will be rejected by a runtime error on 3.2.(See also #1040)
