CI: use Ubuntu 22.04

The CI workflows were running jobs using Ubuntu 20.04.
The mentioned version has been unsupported since 2025-04-15.

Therefore, the workflow files are adjusted to use Ubuntu 22.04.
Moreover, Swift SDK's version is raised from 5.4.3 to 5.9.2, because
the older version is not available for Ubuntu 22.04.
