Remove the Sharing experiments section from Get Started > Experiments
We should remove the Sharing experiments section since it adds more complexity to the Get Started tutorial than there needs to be since users have to set up a Git remote as well as a DVC remote. We don't go over this at any other point in the tutorial.
If a user clones the get started repo, it works fine, but if they are following along there are some roadblocks they might run into with getting things set up. For example, I ran into a weird credentials issue with my Git remote and ended up working with @dberenbaum to do a crazy workaround.
Overall, it clouds up the purpose of this section which is running experiments.
Update the git add command for Get Started > Metrics, Parameters, and Plots
In the Comparing iterations section, users can get empty Old and Change values when they run dvc metrics diff because the dvc.lock and dvc.yaml are missing from the git add.
We need to update the command to be git add dvc.lock dvc.yaml scores.json prc.json roc.json.
@flippedcoder Do you mind separating these whenever you have a chance? We try to be pretty strict about keeping issues logically separate so that one part of an issue doesn't block the rest of the issue from being resolved.
Checkboxes could also work, or be a good first step.
May also be good to see if we can consolidate with #1943.
We should also consolidate this one with https://github.com/iterative/dvc.org/issues/2496 cc @iesahin
