## Summary

This PR addresses a bug in the `flake8-simplify` rule `SIM905`
(split-static-string) where `str.split(maxsplit=0)` and
`str.rsplit(maxsplit=0)` produced incorrect results for empty strings or
strings starting/ending with whitespace. The fix ensures that the
linting rule's suggested replacements now align with Python's native
behavior for these specific `maxsplit=0` scenarios.

## Test Plan

1. Added new test cases to the existing
`crates/ruff_linter/resources/test/fixtures/flake8_simplify/SIM905.py`
fixture to cover the scenarios described in issue #18069.
2.  Ran `cargo test -p ruff_linter`.
3. Verified and accepted the updated snapshots for `SIM905.py` using
`cargo insta review`. The new snapshots confirm the corrected behavior
for `maxsplit=0`.
