Fix re expression SyntaxWarning in cache.py
Changes:
Fix re expression `SyntaxWarning` in `cache.py`
The regular expression in lib/python/mod_python/cache.py contains
invalid escape sequences. The escape character (\ aka backslash) of
regular expressions collides with the escape character
(also \ aka backslash) of Python string literals.
Since Python 3.12 any invalid escape sequences in Python's usage of the
backslash in string literals now generate a SyntaxWarning and in the
future this will become a SyntaxError. Previous Python versions also
noted similar future deprecation warnings.
See https://docs.python.org/3.12/library/re.html for more details.
