fix: add missing python3-yaml to runtime dependencies (LP: #2084586) (#…

python3-yaml is required for snap management when parsing snap
assertions. Without it, the landscape-client service fails to start.
It's often already installed in Ubuntu installations, so sometimes it
works without being an explicit dependency.
This change ensures that it is an installed dependency.
