Description: 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.
