Fix SyntaxError by replacing regular string regex to raw string Regex in python 3.12

[GameSetAndMatch]

Description

Pytest tests fail when importing the azure-search-documents==11.5.1 library due to syntax error when using python 3.12.

Related documentation about the issue

As documented in this python 3.12 change information, SyntaxWarning are now replaced by SyntaxError.

A backslash-character pair that is not a valid escape sequence now generates a SyntaxWarning, instead of DeprecationWarning. For example, re.compile("\d+.\d+") now emits a SyntaxWarning ("\d" is an invalid escape sequence, use raw strings for regular expression: re.compile(r"\d+.\d+")). In a future Python version, SyntaxError will eventually be raised, instead of SyntaxWarning. (Contributed by Victor Stinner in gh-98401.)

and also the python regex doc

In addition, special escape sequences that are valid in regular expressions, but not valid as Python string literals, now result in a DeprecationWarning and will eventually become a SyntaxError, which means the sequences will be invalid if raw string notation or escaping the backslashes isn’t used.

To fix the issues, I added the raw string notation before the "\W+" patterns where necessary.

Sure. It is open-source project, and you can download the code and use pip install -e <path_to_the_search_library> to install it.

We will have a release with the fix in Nov.

And to clarify, this will be a preview release. The feature is not ready to GA yet.
