Remove notebook export options that are not supported by SMD

[andychoquette]

Description

PDF, webPDF, qtpng, and qtpdf exports fail in SageMaker Unified Studio and SageMaker Studio JL, requiring extra configuration and package installations to function. Many of these dependencies are very large, so they are not being considered to be included in the SageMaker Distribution at this time. This PR disables these exporters.

requiring extra configuration and package installations to function.

Are we sure users won't install and use the features? Given that these require additional packages - Maybe we notify them somehow but removing them altogether means such users would also have to manually update the server config and restart Jupyter which we do not advertise from what I know?

Mainly worried because PDF at least seems like a very basic use case.
