Fix uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger error on CI

[andrykonchin]

Explicit requiring the logger library is needed for Rails 6.0-7.0. The issue is already fixed in Rails 7.1 and above.

See the following for details:

• Rails 7.0.8 fails to create an app with most recent concurrent-ruby version rails/rails#54260
• Update requires in LoggerThreadSafeLevel rails/rails#49372

Example of the exception:

NameError:
  uninitialized constant ActiveSupport::LoggerThreadSafeLevel::Logger

      Logger::Severity.constants.each do |severity|
