Remove FairlearnDashboard and replace it with matplotlib-based plots (#…

…766)

With a slight delay (originally targeted for April) I'm finally removing the `FairlearnDashboard` since a newer version already exists in `raiwidgets`. The documentation is updated to instead use the plots @MiroDudik created with a single line directly from the `MetricFrame`. In the future we want to add more kinds of plots as already mentioned in #758 #666 and #668 . Specifically, the model comparison plots do not yet have a replacement yet.

Note that the "example" added to the `examples` directory is not shown under "Example notebooks" on the webpage, which is intentional since it's technically not a notebook.

This also makes #561 mostly redundant, which I'll close shortly. 
#667 is also directly addressed with this PR as the examples illustrate.
