Add InvariantGlobalization to csproj

[hishamco]

If the invariant config switch is not set or it is set false

• The framework will depend on the OS for the globalization support.
• On Linux, if the ICU package is not installed, the application will fail to start.

I've never heard of this, and reading https://github.com/dotnet/runtime/blob/main/docs/design/features/globalization-invariant-mode.md doesn't make me confident this is a good thing. Doesn't this completely break any globalization support for OC?
