Update urllib3 to 1.26.10

[pyup-bot]

This PR updates urllib3 from 1.26.6 to 1.26.10.

Changelog

1.26.9

===================

* Changed ``urllib3[brotli]`` extra to favor installing Brotli libraries that are still
receiving updates like ``brotli`` and ``brotlicffi`` instead of ``brotlipy``.
This change does not impact behavior of urllib3, only which dependencies are installed.
* Fixed a socket leaking when ``HTTPSConnection.connect()`` raises an exception.
* Fixed ``server_hostname`` being forwarded from ``PoolManager`` to ``HTTPConnectionPool``
when requesting an HTTP URL. Should only be forwarded when requesting an HTTPS URL.

1.26.8

===================

* Added extra message to ``urllib3.exceptions.ProxyError`` when urllib3 detects that
a proxy is configured to use HTTPS but the proxy itself appears to only use HTTP.
* Added a mention of the size of the connection pool when discarding a connection due to the pool being full.
* Added explicit support for Python 3.11.
* Deprecated the ``Retry.MAX_BACKOFF`` class property in favor of ``Retry.DEFAULT_MAX_BACKOFF``
to better match the rest of the default parameter names. ``Retry.MAX_BACKOFF`` is removed in v2.0.
* Changed location of the vendored ``ssl.match_hostname`` function from ``urllib3.packages.ssl_match_hostname``
to ``urllib3.util.ssl_match_hostname`` to ensure Python 3.10+ compatibility after being repackaged
by downstream distributors.
* Fixed absolute imports, all imports are now relative.

1.26.7

===================

* Fixed a bug with HTTPS hostname verification involving IP addresses and lack
of SNI. (Issue 2400)
* Fixed a bug where IPv6 braces weren't stripped during certificate hostname
matching. (Issue 2240)
