Remove duplicate typeprovider target

[baronfel]

The NetSdk.targets had a duplicate CollectFSharpDesignTimeTools target, and so now they don't.

The other, still-present target is at

fsharp/src/fsharp/FSharp.Build/Microsoft.FSharp.NetSdk.targets

Lines 61 to 67 in 4d1e140

	<Target Name="CollectFSharpDesignTimeTools" BeforeTargets="BeforeCompile" DependsOnTargets="_GetFrameworkAssemblyReferences">
	<ItemGroup>
	<PropertyNames Include = "Pkg$([System.String]::Copy('%(PackageReference.FileName)').Replace('.','_'))" Condition = " '%(PackageReference.IsFSharpDesignTimeProvider)' == 'true' and '%(PackageReference.Extension)' == '' "/>
	<PropertyNames Include = "Pkg$([System.String]::Copy('%(PackageReference.FileName)%(PackageReference.Extension)').Replace('.','_'))" Condition = " '%(PackageReference.IsFSharpDesignTimeProvider)' == 'true' and '%(PackageReference.Extension)' != '' "/>
	<FscCompilerTools Include = "$(%(PropertyNames.Identity))" />
	</ItemGroup>
	</Target>
