No tutorials/examples datasets

[aheev]

We need to provide sample datasets for the following. Current links are broken

• iceberg-extension
• graph-algorithms
• example-database.md
• python
• rust

I think we should remove the links to the zip files and provide links to huggingface similar to:

https://huggingface.co/datasets/ladybugdb/small-kgs/tree/main

In the process of creating a small repo with a couple of scripts to generate datasets. Each dataset would come in 3 flavors (may be 5 if we add some neo-parquets).

I'm also thinking the datasets in the main ladybug repo are hogging disk and making clones slower, which could be a problem attracting more contributors.

I'm considering splitting the main repo into two, so history would be preserved. But commit hashes will be lost and people will need to clone both the repos again.
