[FR] Improvements to the deepfakes in politics example

[brimoor]

Here are a few suggestions for improving the examples/deepfakes_in_politics example:

• Some of the screenshots don't quite match the dataset that user gets when they download from the link
• I see that not all videos have tags indicating the true speaker. It would be nice if you'd add tags for the missing videos
• I used the view bar to sort by confidence, to show the most confident real/fake video. Although there are only 7 videos, it would be nice to show the user that such operations are possible via the view bar
