Finally adds support for more Blåhaj mods, most notably the fabric replushed port, and thus newer versions! Yay!

• Oops! I accidentally had Blåvingad as Soft Toy Blue Shark and not Soft Toy Blue Whale, and didn't notice for two months. That's fixed now.

• Updates the pack format version to 1.20's version
• Added support for Blåvingad
• Clean up the language file

Initial Release! 🎉

• Renames Blåhaj and Klappar Haj
