+"""Update specific music disc description localization keys across all language files.
+
+Keys updated:
+  item.minecraft.music_disc_chirp.desc -> Big F - Fysik
+  item.minecraft.music_disc_blocks.desc -> Yunge Kutta - Plugga
+  item.minecraft.music_disc_13.desc -> Yunge Kutta - Nabla Aura
+  item.minecraft.music_disc_11.desc -> Yunge Kutta - Linjären
+  item.minecraft.music_disc_cat.desc -> Yunge Kutta - F (Skålar & Pokaler)
+
+Only modifies files where at least one of the keys exists and value differs.
+Preserves key ordering and formatting style (2-space indent) while ensuring a trailing newline.
