fix(#478): ./build.sh works from clean source again. (#486)

This fixes #478, at least for ./build.sh. Attempts to use `dotnet run
--project Yafc` from clean source are still broken, but it doesn't
appear anyone is trying to do that.

Other solutions I tried all seemed to have more pain than benefits:
`dotnet build FactorioCalc.sln --target:Yafc:Publish -r win-x64` would
try to run an explicitly x64 version of I18n.Generate on arm64
processors, or vice versa. Using project-level dependencies requires a
#if to prevent introducing a warning, and adds extra files to the
publish folders.
