Client side page sections not collecting/applying name, collapsible, expanded propeties

When getting and applying templates, some of the newer properties on page sections are ignored. This includes DisplayName, Collapsible, and Expanded, possibly among others.

I believe this will handle extracting the properties and writing them to the template, but I'm not sure about the template -> SP part. I've also not been able to test the below due to some bizarre (unrelated) environment issues.

Start in src/lib/PnP.Framework/Provisioning/ObjectHandlers/Utilities/ClientSidePageContentsHelper.cs and inspect how client-side page section properties are extracted into templates. Verify the template-to-SharePoint direction as well, including DisplayName, Collapsible, and Expanded/IsExpanded, and add or run coverage for the round trip. Done means these properties are preserved when getting and applying templates.
