Add docker for Spark+Iceberg+Nessie+MinIO

Inspired from https://github.com/tabular-io/docker-spark-iceberg

What's the benefit over https://github.com/projectnessie/nessie-demos, which can be run by everyone via a browser without the need of doing the "docker compose dance"?

• User can bring up this docker with other projects like kafka-connect.
  Example: https://github.com/Wuerike/kafka-iceberg-streaming/blob/main/docker-compose.yaml
• Easy to use spark-shell/spark-sql for custom commands testing with Nessie catalog

Nessie demo notebook I thought of adding to this repo also thinking it will be useful for user to understand the Nessie scenarios if they already have this docker running.

The main differences of this repo compared to nessie-demos are:

• examples will be multi-catalog, not only Nessie based
• docker images will be contributed upstream to Iceberg

I think it makes sense to cross link and do everything related to Nessie in nessie-demos. The rest (hive/hdfs/jdbc based catalog) should be in iceland.

Looking forward to contributions to nessie-demos :)
