tests: Fix cookie test compatibility with Python 3.13.4+

Update the test_get_cookie test to handle changes in LWPCookieJar serialization
format introduced in Python 3.13.4+ (see
python/cpython#130631). The upstream change removed
quotes from domain values in cookie strings. Therefore we now use a regex to
match the cookie instead to retain compatibility accross all python versions.
