Added the 1.21.6 panorama textures and updated the pack format to match 1.21.6.

• Restores the panorama to its original state.

Since the panorama differs by version, we’ve separated the panorama changes into a standalone resource pack.

Inside the resource pack folder, there is a Panorama folder containing panorama resource pack files for each version. Select the appropriate one for your version and move it to your resource pack folder to apply it.

• Reverts the changes made to the piston model.
• Reverts the changes made to the sugar cane model and texture.
• Updates the pack.mcmeta pack format to support versions from 1.14 to 1.21.5.
