replace ensure_clean with temp_file in pandas/tests/io/sas/test_sas.py
What:
Replace tm.ensure_clean usage with the pytest temp_file fixture in
pandas/tests/io/sas/test_sas.py.

Why:
The project standard is to use the temp_file pytest fixture instead of the
legacy ensure_clean helper. This is one small PR toward #62435.

Changes:

• test_sas_read_no_format_or_extension: changed signature to accept temp_file
  and pass temp_file directly to read_sas().

Local verification:

• Ran the file tests locally:
  pytest -q pandas/tests/io/sas/test_sas.py
  pytest -q pandas/tests/io/sas/test_sas.py::TestSas::test_sas_read_no_format_or_extension
• Pre-commit hooks:
  pre-commit run --all-files

Notes:

• This PR only updates a test file and preserves test semantics.
• The change is a small, direct replacement and does not close the overall
  issue; it is part of the multi-PR effort to address TST: Replace ensure_clean utility function with the temp_file pytest fixture #62435 (xref TST: Replace ensure_clean utility function with the temp_file pytest fixture #62435).
