Remove AssemblyOriginatorKeyFile from MAUI project

[frederikprijck]

Changes

We do not need to strong-name our files file for MAUI, so removing that reference to the SNK file.

For .NET Core and .NET 5+, strong-named assemblies do not provide material benefits. The runtime never validates the strong-name signature, nor does it use the strong-name for assembly binding.
