Puddles 2.0.0: Now fully server-sided!

- Port to 1.21
- Utilize Polymer and ServerTranslationsAPI for fully server-side functionality (Doesn't even require resourcepacks)
- Instead of breaking, puddles will now create a splash effect when mined
- Puddles no longer slow down walking (Sprinting still gets interrupted; this is not fixable, closes #2)
- Fixed #13
- Fixed #11
