Add `logger` to runtime dependency

[koic]

This PR adds logger to runtime dependency to suppress the following warning:

$ ruby -v
ruby 3.4.0dev (2024-06-14T03:14:32Z master 2677ab1607) [x86_64-darwin23]
$ cd path/to/rubocop
$ bundle exec rake
/Users/koic/.rbenv/versions/3.4-dev/lib/ruby/gems/3.4.0+0/gems/yard-0.9.36/lib/yard/logging.rb:3:
warning: logger was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.5.0.
Add logger to your Gemfile or gemspec.

This change is aimed at Ruby 3.5 and will start showing warnings from Ruby 3.4: https://github.com/ruby/ruby/commit/d7e558e

To maintain the following behavior, the dependency will be added in the gemspec to resolve this. https://github.com/lsegal/yard/blob/v0.9.36/lib/yard/logging.rb#L3-L9
