Bug 282733 – Bump minimum Python version to 3.9

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Sam Sneddon [:gsnedders]]

I don't believe any port needs Python 3.9 support in any of our tooling.

As I understand it:

* Xcode 14 (macOS Ventura 13 aligned) ships with Python 3.9.6
* Xcode 15 (macOS Sonoma 14 aligned) ships with Python 3.9.6
* Xcode 16 (macOS Sequoia 15 aligned) ships with Python 3.9.6
* Ubuntu 22.04 ships with Python 3.10.6
* Ubuntu 24.04 ships with Python 3.12.3
* Debian 12 ships with Python 3.11.2

The only port I'm not sure about is wincairo, but I believe that's typically been using pretty up-to-date Python?
