V8 : Spiked ring + tutorials

Welcome to version 8!

• Added spiked ring, use it in the different calculators! (In beta, might be slightly off)
• Added tutorial popups to tell you how to use the calculators!
• Updated magic special attack formula, previously it was too low.
• Refactored the code, now the training page should be a little bit smoother
• Updated Material3 version (this shouldn't change anything, maybe fix display bugs on some devices)
• Updated some translations for the new features! Thanks to the translate team
