Warning on Ruby 3.3 because of requiring `syslog` package

[Earlopain]

Ruby 3.3 will issue a warning when requiring syslog, Ruby 3.4 will raise an error. https://github.com/ruby/ruby/blob/master/doc/NEWS/NEWS-3.3.0.md#stdlib-updates

I'm talking about these lines of code:

logging/lib/logging.rb

Lines 9 to 15 in df41715

	begin
	require 'syslog'
	HAVE_SYSLOG = true
	rescue LoadError
	HAVE_SYSLOG = false
	end

This already handles the absense of syslog which is good so the gem will not break (much) in the future because of this. However, on Ruby 3.3 a warning message is logged nontheless. Users on linux that use the syslog appender will have that class be undefined on Ruby 3.4.

/home/user/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/logging-2.3.1/lib/logging.rb:10: warning: syslog was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add syslog to your Gemfile or gemspec. Also contact author of logging-2.3.1 to add syslog into its gemspec.

This one is a little more critical though:

ArgumentError: comparison of String with nil failed (ArgumentError)

    msg = " #{RUBY_VERSION < SINCE[gem] ? "will no longer be" : "is not"} part of the default gems since Ruby #{SINCE[gem]}."
                             ^^^^^^^^^^

Ruby bug 😞 https://bugs.ruby-lang.org/issues/20450

I only get this with the logging gem though 🤣

Thanks for the feedback
