rspec testsuite fails with ruby 3.3.0dev

[mtasaka]

With ruby 3.3.0dev ( I tested ruby/ruby@6d7730a ), mixlib-log git head ( 8643e33 ) rspec testsuite causes error like:

$ rspec spec

This is due to change in ruby Logger:
ruby/ruby@194520f
ruby/logger#85

and almost the same fix as steveklabnik/mono_logger#12 is needed.
