A bit more Music Discs!

• Retextured Dog disc and Dog&Cat Disc

• Added Disc fragments for Disc 11 since now you cannot obtain "Eleven" by creepers, you need to fix the disc 11 in a smithing table
• Disc fragments (for now) are obtained through wandering traders

• Added the discs to a tag so it should be able to work with my other mod "Disc Holder"

• Updated the textures of the discs since the colors were a bit off, and also added a photo texture on the long song disc inspired by the album cover of the song.

I've added two new advancements and added another music disc with another song from C418 named "long songs are for people who don't have time to make them short"
