Make the "setup" notebook functional

[promisinganuj]

The initial version of the "setup" notebook is already deployed using Terraform Fabric provider. This item is to make this notebook functional by performing the following:

Depends on merging of #862

DoD

• Address the issue where the shortcut can't be accessed without it being accessed once (some sort of authentication issues).

  import os, time
  
  config = configparser.ConfigParser(interpolation=configparser.ExtendedInterpolation())
  config.read(f"{local_data_mount_path}/{config_file_path}")
  

• Migrate some of the comments from the notebook and move it to the markdown in GitHub.
• Decide and update the usage of default lakehouse vs direct account via mounts.
• Review the code and see if we can move some of the content as a library. #1007
• Update the main README.md.
  • Add "How to use the sample" section.
  • Explain the manual process of uploading config/reference data to ADLS gen2.
  • Explain the manual process of uploading custom python library/environment.yml to Fabric environment.
  • Explain the steps to run the notebook.
  • Explain the output of the run. i.e., tables created, reference data loaded.

Out of scope

• Automation of uploading config/reference data to the ADLS gen2 storage.
• Running of the notebook via Fabric pipeline (though it's already integrated).

workaround is to list the contents of local_data_mount_path.

import os
print(os.listdir(local_data_mount_path))
