Log Message:
py-pip-audit: update to 2.4.4.

## [2.4.4]

### Changed

* `pip-audit` is now a PyPA member project, and lives under
  [`pypa/pip-audit`](https://github.com/pypa/pip-audit)!

* Improved error message for when unpinned URL requirements are found during an
  audit with the `--no-deps` flag
  ([#355](https://github.com/pypa/pip-audit/pull/355))

### Fixed

* Fixed an issue where packages on PyPI with no published versions trigger a
  dependency resolution failure instead of being skipped
  ([#357](https://github.com/pypa/pip-audit/pull/357))

* Fixed an incorrect assertion triggering for non-editable URL requirements that
  don't have an egg fragment
  ([#359](https://github.com/pypa/pip-audit/pull/359))
