tome: aspnetcore runtime, gapps wrapping, glib at runtime

Three separate reasons the packaged build didn't behave like the one Rider
launches:

- dotnet-runtime must be aspnetcore_10_0, not runtime_10_0. Tome.App's
  runtimeconfig.json requires Microsoft.AspNetCore.App as well as
  Microsoft.NETCore.App, because Photino hosts a local Kestrel server, and
  only the aspnetcore bundle ships it.
- wrapGAppsHook3, so gappsWrapperArgs get spliced into buildDotnetModule's
  own wrap step (it sets dontWrapGApps itself; same pattern as nixpkgs'
  libation). Without it nothing sets XDG_DATA_DIRS/GSETTINGS_SCHEMA_DIR, so
  GTK/WebKitGTK found neither the icon theme nor GTK settings — missing icons
  and a denser default font than in an already-initialized session.
- glib in runtimeDeps. It doesn't arrive via gtk3/webkitgtk's RPATH because
  the consumer is Photino.Native.so, a prebuilt binary out of the nuget
  package rather than something Nix built and patched.

tome-deps.json is the regenerated nuget lock for the aspnetcore switch.
