py-urllib3: updated to 1.25.6

1.25.6:
* Fix issue where tilde (``~``) characters were incorrectly
  percent-encoded in the path.

1.25.5:
* Add mitigation for BPO-37428 affecting Python <3.7.4 and OpenSSL 1.1.1+ which
  caused certificate verification to be enabled when using ``cert_reqs=CERT_NONE``.

1.25.4:
* Propagate Retry-After header settings to subsequent retries.
* Fix edge case where Retry-After header was still respected even when
  explicitly opted out of.
* Remove dependency on ``rfc3986`` for URL parsing.
* Fix issue where URLs containing invalid characters within ``Url.auth`` would
  raise an exception instead of percent-encoding those characters.
* Add support for ``HTTPResponse.auto_close = False`` which makes HTTP responses
  work well with BufferedReaders and other ``io`` module features.
* Percent-encode invalid characters in URL for ``HTTPConnectionPool.request()``
