Do not use 'Generate NuGet package on build' in .csproj

[LottePitcher]

Feature summary

This would slow down the build process in larger sites and also, perhaps, lead to caching issues

Additional details

If this was unticked then the nuget package would not get automatically generated when Visual Studio builds:

You should only look to test the nuget package once you've finished testing via the test site, and want to test that the nuget install itself works. So probably makes sense to use a dotnet pack command for that at the appropriate time instead.

So when you are ready to generate the nuget package for local testing use the command line with something like

dotnet pack --configuration Release /p:Version=1.0.0-rc001 --no-build --output
