devel/ruby-activesupport52: update to 5.2.4.2

Update ruby-activesupport52 to 5.2.4.2.

## Rails 5.2.4.1 (December 18, 2019) ##

*  No changes.

## Rails 5.2.4 (November 27, 2019) ##

*  Make ActiveSupport::Logger Fiber-safe. Fixes #36752.

    Use `Fiber.current.__id__` in `ActiveSupport::Logger#local_level=` in order
    to make log level local to Ruby Fibers in addition to Threads.

    Example:

        logger = ActiveSupport::Logger.new(STDOUT)
        logger.level = 1
        p "Main is debug? #{logger.debug?}"

        Fiber.new {
          logger.local_level = 0
          p "Thread is debug? #{logger.debug?}"
        }.resume

        p "Main is debug? #{logger.debug?}"

    Before:

        Main is debug? false
        Thread is debug? true
        Main is debug? true

    After:

        Main is debug? false
        Thread is debug? true
        Main is debug? false
