[issue35824] http.cookies._CookiePattern modifying regular expressions

[MeiK]

You are right, I saw the agreed way of parsing in RFC6265[1], it seems that you should not use regular expressions.

I used http.cookiejar to update the code, but it failed to pass the test: https://github.com/python/cpython/blob/master/Lib/test/test_http_cookies.py#L19. However, other languages and libraries (JavaScript, Requests, http.cookiejar, etc.) cannot parse it. It seems that the contents of the brackets should be escaped. Is this a wrong test case?

I updated the code[2] using http.cookiejar. Is this a good idea?

English is not my native language; please excuse typing errors.
