Update Ruby.ignore to ignore .byebug_history file

The file `.byebug_history` is generated when using the popular https://github.com/deivid-rodriguez/byebug gem for debugging in Ruby. It contains a list of commands the user has run while debugging, which should not be committed to the repository. The author of the gem agrees with this here: https://github.com/deivid-rodriguez/byebug/issues/204#issuecomment-178238302

I have copied this from the Rails gitignore here: https://github.com/github/gitignore/blob/f908e51bcf38ae5ede449c55189a7b25d8c507cc/Rails.gitignore#L45
