[PATCH] ci: update 'static-analysis' to Ubuntu 22.04

From: Derrick Stolee <derrickstolee@github.com>

GitHub Actions scheduled a brownout of Ubuntu 18.04, which canceled all runs of the 'static-analysis' job in our CI runs. Update to 22.04 to avoid this as the brownout later turns into a complete deprecation.

The use of 18.04 was set in d051ed77ee6 (.github/workflows/main.yml: run static-analysis on bionic, 2021-02-08) due to the lack of Coccinelle being available on 20.04 (which continues today).

    I initially asked about this [2]. Thanks to Matthias Aßhauer for
    pointing out that 22.04 has Coccinelle available [3].
