This change contains the following changes:
* Update QDK to version 0.12.20100504.
* Add the IQSharpLoadAutomatically property to each .csproj that will cause IQ# to load the listed packages at initialization time.
* Remove the %package Microsoft.Quantum.Katas and %workspace reload calls from each notebook, since those are no longer necessary with the above change.
