Prepare 1.0.60/1.4.0 release: rebuild plugin DLLs, bump package.json

Removing the public asset path attribute is breaking. Runs
scripts/build-unity-package.ps1 -UpdateTemplate to refresh the tracked
plugin DLLs/pdbs in unity/org.gamecult.cultlib/Runtime/Plugins, and bumps
unity/org.gamecult.cultlib/package.json to 1.0.60 and
src/GameCult.Unity/Assets/Caching/package.json to 1.4.0 (dependency bumped
to cultlib 1.0.60). Tags are the next, separate step.
