using serverless compute

Test 3

Create a DABs job config for notebooks/data_processing.ipynb using a classic
cluster with 2 workers

Test 4

Create a job config for running src/transform.py Databricks notebook with
a 4-worker cluster

Test 5

Configure a DABs job to run a Python script task at scripts/load_data.py

Test 6

Set up a job to run Python script src/etl_batch.py with a cluster of 3

I'm not sure databricks-cli fully covers it. Maybe something like databricks-shared would be better, if we need to extend the name?

This was intended as a "shared" skill that should always be consumed for all work done. Kind of like our system prompt. And then it has some progressive disclosure for shared work (auth, installation, DABs, data exploration). Especially data exploration doesn't really fit the mold here since it's not a CLI activity. The CLI is a means to an end.

I will close this PR and try one as databricks-core, which seems like a good representation to me and won't conflict with other skills being distributed. Please let me know if that name should be refined.
