Fix Razor Scoped CSS so it doesn't cause errors in iOS/MacCatalyst bundle targets

[Eilon]

In PR #2938 a temporary workaround was added to ensure that Razor Scoped CSS is not "seen" by the iOS/MacCatalyst bundling targets because they cause an error.

This is the workaround:
https://github.com/dotnet/maui/pull/2938/files#diff-a403e09c8175f7c626397dc3695070bc822b977346468fe4cc11504388bbc68bR39-R41

And this is the error it would otherwise cause (without the workaround):

Shared/MainLayout.razor.css The path '../../../../../../../../templatesTest/mauiblazor Space-Dash/Shared/MainLayout.razor.css' would result in a file outside of the app bundle and cannot be used.
         [/Users/builder/azdo/_work/1/templatesTest/mauiblazor Space-Dash/mauiblazor Space-Dash.csproj]
Shared/NavMenu.razor.css The path '../../../../../../../../templatesTest/mauiblazor Space-Dash/Shared/NavMenu.razor.css' would result in a file outside of the app bundle and cannot be used.
         [/Users/builder/azdo/_work/1/templatesTest/mauiblazor Space-Dash/mauiblazor Space-Dash.csproj]
