Subject: [PATCH] tests/extmod/re_sub.py: Fix test execution on Python 3.13.

This commit fixes a test failure for `extmod/re_sub.py` where the code,
whilst being correct, would not make the test pass due to a newer
Python version than expected.

On Python 3.13, running `tests/extmod/re_sub.py` would yield a
deprecation warning about `re.sub` not providing the match count as a
keyword parameter.  This warning would be embedded in the expected test
result and thus the test would always fail.
