Docs feedback: Google Chat Integration: Thread Support using REPLY_MESSAGE_FALLBACK_TO_NEW_THREAD

https://docs.gitlab.com/ee/user/project/integrations/hangouts_chat.html#enable-the-integration-in-gitlab

Due to Google Chat changes, a workaround is to have the integration web link append &messageReplyOption=REPLY_MESSAGE_FALLBACK_TO_NEW_THREAD

^ This fixes it and restores "thread support" for gitlab integration with Google Chat.
