Bumps pip from 21.3.1 to 22.2.1.

Changelog

Sourced from pip's changelog.

22.2.1 (2022-07-27)

Bug Fixes

• Send the pip upgrade prompt to stderr. ([#11282](https://github.com/pypa/pip/issues/11282) <https://github.com/pypa/pip/issues/11282>_)
• Ensure that things work correctly in environments where setuptools-injected distutils is available by default. This is done by cooperating with setuptools' injection logic to ensure that pip uses the distutils from the Python standard library instead. ([#11298](https://github.com/pypa/pip/issues/11298) <https://github.com/pypa/pip/issues/11298>_)
• Clarify that pip cache's wheels-related output is about locally built wheels only. ([#11300](https://github.com/pypa/pip/issues/11300) <https://github.com/pypa/pip/issues/11300>_)

22.2 (2022-07-21)

Deprecations and Removals

• Remove the html5lib deprecated feature flag. ([#10825](https://github.com/pypa/pip/issues/10825) <https://github.com/pypa/pip/issues/10825>_)
• Remove --use-deprecated=backtrack-on-build-failures. ([#11241](https://github.com/pypa/pip/issues/11241) <https://github.com/pypa/pip/issues/11241>_)

Features

• Add support to use truststore <https://pypi.org/project/truststore/>_ as an alternative SSL certificate verification backend. The backend can be enabled on Python 3.10 and later by installing truststore into the environment, and adding the --use-feature=truststore flag to various pip commands.

  truststore differs from the current default verification backend (provided by certifi) in it uses the operating system’s trust store, which can be better controlled and augmented to better support non-standard certificates. Depending on feedback, pip may switch to this as the default certificate verification backend in the future. ([#11082](https://github.com/pypa/pip/issues/11082) <https://github.com/pypa/pip/issues/11082>_)

• Add --dry-run option to pip install, to let it print what it would install but not actually change anything in the target environment. ([#11096](https://github.com/pypa/pip/issues/11096) <https://github.com/pypa/pip/issues/11096>_)

• Record in wheel cache entries the URL of the original artifact that was downloaded to build the cached wheels. The record is named origin.json and uses the PEP 610 Direct URL format. ([#11137](https://github.com/pypa/pip/issues/11137) <https://github.com/pypa/pip/issues/11137>_)

• Support PEP 691 <https://peps.python.org/pep-0691/>. ([#11158](https://github.com/pypa/pip/issues/11158) <https://github.com/pypa/pip/issues/11158>)

• pip's deprecation warnings now subclass the built-in DeprecationWarning, and can be suppressed by running the Python interpreter with -W ignore::DeprecationWarning. ([#11225](https://github.com/pypa/pip/issues/11225) <https://github.com/pypa/pip/issues/11225>_)

• Add pip inspect command to obtain the list of installed distributions and other information about the Python environment, in JSON format. ([#11245](https://github.com/pypa/pip/issues/11245) <https://github.com/pypa/pip/issues/11245>_)

• Significantly speed up isolated environment creation, by using the same sources for pip instead of creating a standalone installation for each environment. ([#11257](https://github.com/pypa/pip/issues/11257) <https://github.com/pypa/pip/issues/11257>_)
