Issue:
Fix broken dataset links in examples

<!--
You can obtain the Modin version with

python -c "import modin; print(modin.__version__)"
-->

### Describe the problem
Dataset links that refers to `s3://modin-datasets` is broken (e.g., inside h2o_runner, mortgage_runner).
We should point the examples to alternative dataset paths.



Discussion:
@gshimansky, could you issue a PR where wrong links are replaced to correct ones?
I am not sure where mortgage (used in `examples/cluster/mortgage-runner.py`) datasets was moved. Currently `s3://modin-datasets` contents looks like this:

@modin-project/modin-core, @modin-project/modin-omnisci, any thoughts on this?
I don't think we can make this dataset public, so we would have to either remove this example or mark as deprecated.
I guess we probably should remove it to not confuse our users.
