azure-pipeline: run static-analysis on jammy

This is inspired by d051ed7 (.github/workflows/main.yml: run
static-analysis on bionic, 2021-02-08) and by ef46584 (ci: update
'static-analysis' to Ubuntu 22.04, 2022-08-23), adapted to the Azure
Pipeline.

When Azure Pipelines' build agents transitioned 'ubuntu-latest' from
18.04 to 20.04, it broke our `static-analysis` job, since Coccinelle
was not madeavailable on Ubuntu focal (it is only available in the
universe suite).

This is not an issue with Ubuntu 22.04, but we will only know whether it
is an issue with 24.04 when _that_ comes out. So let's play it safe and
pin the `static_analysis` job to the latest Ubuntu version that we know
to offer a working Coccinelle package.
