refactor: Refactor pandas option usage for backward compatibility

- Introduce the `optional_option_context` helper to replace the direct
  use of `pd.option_context("future.no_silent_downcasting", True)`,
  ensuring compatibility with older pandas versions that lack this
  option.
- Update the `future.infer_string` test to run only on pandas >= 2.1,
  where it is applicable.
