python3-pip: fix CVE-2023-5752

When installing a package from a Mercurial VCS URL (ie "pip install
hg+...") with pip prior to v23.3, the specified Mercurial revision could
be used to inject arbitrary configuration options to the "hg clone" call
(ie "--config"). Controlling the Mercurial configuration can modify how
and which repository is installed. This vulnerability does not affect
users who aren't installing from Mercurial.
