Updated to 1.21.11!

Not a lot of new features here on Vanilla+, but over on Vanilla++ there's a new Music Disc, a new Structure, and 16 new items used for Trim Materials! Also, there's a more updated Vanilla+ video on the main page that goes over most features in both Vanilla+ and Vanilla++! Check it out!

• Spears: With the new Vanilla implementation of Spears, my versions of them have been removed. Instead, the Amethyst, Emerald, Quartz, and Resin Spears have been updated to match the new Vanilla spears.
• Misc. Changes: the glitch where upgrading an Emerald gear piece to Netherite makes it retain its lower durability should be fixed now. Additionally, some items that had weird appearances in Shelves have been fixed.
