Subject: [PATCH] Don't require io/wait on 3.2 or higher

io/wait functionality has been in core Ruby since 3.2. It was a
default gem in 3.0 and 3.1 and before that it was a non-gem
standard library. With the "1.0.0" release of io-wait it is now
deprecated and warns when loaded. This patch modifies the require
to only run under Ruby versions earlier than 3.2.

See ruby/io-wait#79 and ruby/io-wait#80
