Upgrade bundled pip to 24.3

[ThomasWaldmann]

Feature or enhancement

Proposal:

ensurepip's bundled version of pip gets updated to the current latest 24.3.

Background:

The pip 24.2 wheel bundled into current python releases is broken and does not work at all on old macOS releases (like e.g. macOS Sierra / High Sierra).

This issue was fixed and released as pip 24.3, so this ticket is intended as a reminder to not forget to update the bundled pip in CPython to at least that version.

There is still the broken pip 24.2 there:

• https://github.com/python/cpython/tree/3.12/Lib/ensurepip/_bundled
• https://github.com/python/cpython/tree/3.13/Lib/ensurepip/_bundled
• https://github.com/python/cpython/tree/main/Lib/ensurepip/_bundled

Please replace all pip 24.2 by >=24.3.

CPython versions tested on:

3.12, 3.13, CPython main branch

Operating systems tested on:

macOS

@sbidoul is planning on doing it soonish: pypa/pip#12941 (comment)

We're not in a rush, the next releases aren't for a while, so it's good to let things settle and any regressions shake out.

• 2024-11-19: 3.14.0a2
• 2024-12-03: 3.12.8
• 2024-12-??: 3.13.1

Yep, no worries, I keep an eye on the timeline. Currently waiting on a packaging release to address pypa/pip#13053, which should also happen soon, as @pradyunsg is on it.
