* ci, examples : add package-lock.json to examples addon node

This commit commits the package-lock.json file for examples/addon.node.

This is needed to make the CI workflow work properly and after we
started pinning the action versions in the workflow, the CI started
failing because the package-lock.json was not committed. At least that
is what I think is happening.

* ci: use node 20.x and 22.x instead of 16.x and 18.x

* fix CMakeLists.txt target properties for addon.node
