Sequel: relax Ruby requirement for Timed pool

Accommodate Sequel v5.85.0, which has made the timed connection pool the
default for Ruby 3.2+ by always  permitting the use of a timed
connection pool for explain plan generation in a Ruby 3.2+ context
(previously only a Ruby 3.4+ context would work).
