github: enforce testing pylibfdt and yaml support

The Ubuntu runner was not building the yaml support as it's using Ubuntu
22 (jammy) which uses libyaml 0.2.2, but the build requires libyaml
0.2.3. Switch to Ubuntu 23 which has libyaml 0.2.5.

This was not detected by the runner as the Yaml feature defaults to
"auto" which turns off if it fails to find the dependency. In the runner
force yaml to enabled so if it fails to build it will trigger a build
failure.

We also force python support for the same reason.
