Corresponding repo to play with: https://studio.iterative.ai/user/shcheklein/views/example-get-started-r7898c5e32

(a few lines in the PR will be uncommented / reverted before actual merge, after testing)

It changes example get started:

• To use a clean dataset (thus 2.5x smaller)
• Less number of features (3000 -> 100/200). Since dataset is better it's now enough - should be way better memory footprint
• More plots - confusion matrix + forest analysis (most useful feature)
• CML report includes confusion matrix
• Two branches - more data, hyperparams tuning

I've forced push multiple times in this repo, to make branch name and description less confusing closing this in favor of https://github.com/iterative/example-repos-dev/pull/114
