feat(mods): add Doggy Talents Next, drop Etched and Grassier Grass

Doggy Talents Next 1.19.1 (NeoForge 1.21.1) overhauls the wolf with a
talent/bond system and companion AI. Better Dogs X DTN 1.2.2 adds its
cosmetic skins; Modrinth only lists a 1.21 NeoForge build, but its
mods.toml declares neoforge >=20.5 and minecraft >=1.18.2, so it loads
on the pack's 21.1.251.

Remove Etched: a second disc/recording pipeline beside music-disc-maker,
duplicating blank discs, boomboxes and albums.

Remove Grassier Grass: its only open risk was shader compatibility with
the shipped Complementary Reimagined.
