Pass uri to Notebook Serializer functions.

While I was working on helping make https://github.com/TylerLeonhardt/shell-runner-notebooks a polyglot shell runner, I realized that it's not possible to deserialize the source of the notebook depending on the file name.

In the extension there is one serializer to take .ps1 files into a Notebook by changing the file to be .Notebook.ps1. The underlying file stays the same but the markdown and scripts are parsed out into NotebookData.

The same thing happens for .sh files. But these two don't share the same parsing into NotebookData.

Finally there's a third type of serializer for just Notebook files where the underlying source is standard notebook json.

While these seem like they should be 3 different serializers considering how different they are, the root problem is that you can't register a controller to multiple kinds of serializers, aka viewtypes. But I don't think we should allow controllers to register to many viewtypes, that seems weird.

Right now the extension uses 3 different controllers and 3 different serializers, which is weird for a user who'd expect only one consistent Notebook.
