This PR updates pip from 22.3 to 23.0.1.

Changelog

23.0.1

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

Features
--------

- Ignore PIP_REQUIRE_VIRTUALENV for ``pip index`` (`11671 <https://github.com/pypa/pip/issues/11671>`_)
- Implement ``--break-system-packages`` to permit installing packages into
``EXTERNALLY-MANAGED`` Python installations. (`11780 <https://github.com/pypa/pip/issues/11780>`_)

Bug Fixes
---------

- Improve handling of isolated build environments on platforms that
customize the Python's installation schemes, such as Debian and
Homebrew. (`11740 <https://github.com/pypa/pip/issues/11740>`_)
- Do not crash in presence of misformatted hash field in ``direct_url.json``. (`11773 <https://github.com/pypa/pip/issues/11773>`_)

23.0

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

Features
--------

- Change the hashes in the installation report to be a mapping. Emit the
``archive_info.hashes`` dictionary in ``direct_url.json``. (`11312 <https://github.com/pypa/pip/issues/11312>`_)
- Implement logic to read the ``EXTERNALLY-MANAGED`` file as specified in PEP 668.
This allows a downstream Python distributor to prevent users from using pip to
modify the externally managed environment. (`11381 <https://github.com/pypa/pip/issues/11381>`_)
- Enable the use of ``keyring`` found on ``PATH``. This allows ``keyring``
installed using ``pipx`` to be used by ``pip``. (`11589 <https://github.com/pypa/pip/issues/11589>`_)
- The inspect and installation report formats are now declared stable, and their version
has been bumped from ``0`` to ``1``. (`11757 <https://github.com/pypa/pip/issues/11757>`_)

Bug Fixes
---------

- Wheel cache behavior is restored to match previous versions, allowing the
cache to find existing entries. (`11527 <https://github.com/pypa/pip/issues/11527>`_)
- Use the "venv" scheme if available to obtain prefixed lib paths. (`11598 <https://github.com/pypa/pip/issues/11598>`_)
- Deprecated a historical ambiguity in how ``egg`` fragments in URL-style
requirements are formatted and handled. ``egg`` fragments that do not look
like PEP 508 names now produce a deprecation warning. (`11617 <https://github.com/pypa/pip/issues/11617>`_)
- Fix scripts path in isolated build environment on Debian. (`11623 <https://github.com/pypa/pip/issues/11623>`_)
- Make ``pip show`` show the editable location if package is editable (`11638 <https://github.com/pypa/pip/issues/11638>`_)
- Stop checking that ``wheel`` is present when ``build-system.requires``
is provided without ``build-system.build-backend`` as ``setuptools``
(which we still check for) will inject it anyway. (`11673 <https://github.com/pypa/pip/issues/11673>`_)
- Fix an issue when an already existing in-memory distribution would cause
exceptions in ``pip install`` (`11704 <https://github.com/pypa/pip/issues/11704>`_)

Vendored Libraries
------------------

- Upgrade certifi to 2022.12.7

Improved Documentation
----------------------

- Fixed the description of the option "--install-options" in the documentation (`10265 <https://github.com/pypa/pip/issues/10265>`_)
- Remove mention that editable installs are necessary for pip freeze to report the VCS
URL. (`11675 <https://github.com/pypa/pip/issues/11675>`_)
- Clarify that the egg URL fragment is only necessary for editable VCS installs, and
otherwise not necessary anymore. (`11676 <https://github.com/pypa/pip/issues/11676>`_)

22.3.1

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

Bug Fixes
---------

- Fix entry point generation of ``pip.X``, ``pipX.Y``, and ``easy_install-X.Y``
to correctly account for multi-digit Python version segments (e.g. the "11"
part of 3.11). (`11547 <https://github.com/pypa/pip/issues/11547>`_)
