Made new links for December, sent out the old ones

Hi, I made new reward links for December, I'll be adding new art to them when I start drawing it!You'll find the links under you "Membership" only visible on the browser version, not the app

I also sent out the November links in case you missed them last month!

Let me know if everything works fine!!! :3

PS: for the "reading squad" tier, I'm still working on the new emoji art. I'll add them soon! >.
