fix(text-splitters): remove invalid and duplicate separators in Kotlin, Rust, and Haskell (#37039) ## Summary Fixes four issues in `get_separators_for_language()` in `character.py`: - **Kotlin**: removed `"\ncase "` — `case` is not a Kotlin keyword. Kotlin uses `when` expressions (already present in the list). This was copied from Java/Swift. - **Rust**: removed duplicate `"\nconst "` — appeared twice, once under function definitions and again under control flow statements. - **Haskell**: removed duplicate `"\n:: "` — appeared under function definitions and again under type declarations. - **Haskell**: removed duplicate `"\ndata "` — appeared under type declarations and again under record field declarations. All four are dead separators that never match or produce redundant splits. ## Issue Closes #37038 ## Types of changes - [x] Bug fix ## Checklist - [x] I have read the CONTRIBUTING doc - [x] Lint and unit tests pass locally with my changes
