Add a comment to thread and vice versa to tracker

For the tracker discord integration, when a new bug or to do list item is created, alongside the embed of the new item sent to the log channel, create a thread. Any message sent in the thread is sent in the comments section of the item on the tracker website, and any comments sent in the tracker website, are sent in the thread.

When an item has been implemented or fixed, possibly close the thread
