extensionUtils: Include arrays and objects in serialization

We currently only handle simple types when (de)serializing,
which means we miss keys like "shell-version" and "session-modes".

While there is no immediate use for those, handing arrays and
objects will allow to support the newly added "donate" metadata
in the Extensions app in the future.
