Subject: [PATCH 23/26] website: update Ubuntu 22.04 dependency list

The Ubuntu 22.04 setup command lagged behind the full set of dependencies documented in the build instructions. Update it to install the same dependency set as the newer Ubuntu instructions using Ubuntu 22.04's default package versions.

Normalize dependency minimums to major.minor granularity instead of documenting patch-level package versions. This keeps the build documentation aligned with the supported-version policy without over-specifying distro patch releases.
