Bump rails from 5.2.3 to 5.2.4

Bumps rails from 5.2.3 to 5.2.4.

Release notes

Sourced from rails's releases.

5.2.4

Active Support

• 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
