fa8996b930886da712c09ffe4b58016b36c2ae5b 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.
