Set IsPackable to false in Azure Functions projects (#406)

Updated `Menes.PetStore.Hosting.AzureFunctions.InProcess.csproj`
and `Menes.PetStore.Hosting.AzureFunctions.Isolated.csproj`
to include the property `<IsPackable>false</IsPackable>`.
This change indicates that the projects are not intended to be
packed into NuGet packages, affecting their build and deployment.
