Feedback and Updates I2K workshop

[constantinpape]

• Updates to the workshop
  • Add download script for all relevant models to the preparation (just need to call get_sam_model with the respective model types)
  • Remove the scripting part and create a "What you can do next" instead.
• Feedback from the workshop
  • More readable names for the models
    • Maybe shorten down the model choice and move rest of models to advanced menu options (?)
  • Add download progress to napari
  • +1 request to a macro recording scheme
