Migrate other tutorials to a community folder.

[bitsondatadev]

Create a community-tutorials directory that will contain untested community-driven tutorials.

Warning

This must be updated in tandem with Trino website which links to this repository.

The main motivation here is to have clear healthy maintained code that should be tested as opposed to a pile of tutorials where there's no indication of what is being maintained. This directory will act as an indefinite home for these tutorials and will enable one of three things to happen from this space:

1. You can contribute fixes to this folder similar to any other part of this repository, but I make no promises to maintain these myself.
2. You can add an issue ticket to request taking over the tutorial on your own repository as @metadaddy did with the backblaze tutorial, which now lives here along with a new Iceberg variant.
3. You may also submit a ticket to suggest that there should be a tutorial in the top-level tutorials that I maintain on this website. No guarantees as this will depend on my bandwidth.

Note

I will also update the Readme with a link to other valuable Trino tutorial repositories as I want this repo to also serve as an awesome aggregator to help you find other Trino tutorials.
