fix: correct write_files docstring about directory auto-creation (#1260)

## Summary
- Fixes the Python SDK `write_files` docstring (both sync and async)
which incorrectly stated that writing to a non-existing directory would
produce an error
- The backend actually auto-creates parent directories, consistent with
the `write()` docstring and existing tests
(`test_write_to_non_existing_directory`)

## Test plan
- [x] Verified behavior with a test script — both `write()` and
`write_files()` auto-create nested directories
- [x] Existing tests pass (`test_write_to_non_existing_directory`,
`writeFiles creates parent directories`)
