Merge bitcoin/bitcoin#28211: Bump python minimum supported version to 3.9

Browse Source 
fa25e8b0a1 doc: Recommend lint image build on every call (MarcoFalke)
faf70c1f33 Bump python minimum version to 3.9 (MarcoFalke)
fa8996b930 ci: Bump i686_multiprocess.sh to latest Ubuntu LTS (MarcoFalke)

Pull request description:

  All supported operating systems ship with python 3.9 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python 3.9 features.

  For reference:
  * https://packages.debian.org/bullseye/python3
  * https://packages.ubuntu.com/focal/python3.9
  * FreeBSD 12/13 also ships with 3.9
  * CentOS-like 8/9 also ships with 3.9 (and 3.11)
  * OpenSuse Leap also ships with 3.9 (and 3.11) https://software.opensuse.org/package/python311-base

  This is for Bitcoin Core 27.0 in 2024 (next year), not the soon upcoming 26.0 next month.

After building the container once, you can simply run the last command any time you
want to lint.
Building the container can be done every time, because it is fast when the
result is cached and it prevents issues when the image changes.
