hosting sample at commit https://github.com/dotnet/samples/commit/d7a66aea125b22be11dc717921a802630fcaca46 on debian-x64 with .NET5 sdk installed

Issue description

following readme instructions dotnet run leads to:

The specified runtimeconfig.json [/home/abcdef/src/tmp/testsparse/net5host/bin/Debug/DotNetLib.runtimeconfig.json] does not exist
Init failed: 0x80008093
nativehost: /home/abcdef/src/tmp/testsparse/net5host/src/NativeHost/nativehost.cpp:89: int main(int, char**): Assertion `load_assembly_and_get_function_pointer != nullptr && "Failure: get_dotnet_load_assembly()"' failed.

The file /home/abcdef/src/tmp/testsparse/net5host/bin/Debug/net5.0/DotNetLib.runtimeconfig.json appears to have been created by the build phase though.

Will submit a PR if I find a fix.

this runtimeconfig.json is at INSTALL_DIRECTORY/dotnet/sdk/<version>/dotnet.runtimeconfig.json, in my case it was at: C:\Program Files\dotnet\sdk\7.0.101\dotnet.runtimeconfig.json
