This pulls in a new vendored version of Pip with
the recent fix in https://github.com/pypa/pip/pull/12716 applied in
https://github.com/pex-tool/pip/pull/13. As a result, Pex can run using
vendored Pip under statically linked musl libc CPython interpreters.
This opens the door to bootstrapping newer unpatched Pip's that also
have this same fix (versions 24.2 and later; see: #2471).
