Update the CMS open data example to work with the new configuration-based workflow.

[JaySandesara]

The latest version of nsbi-common-utils is demonstrated currently on the FAIR Universe dataset. The CMS open data example is now outdated and needs to be updated. Great chance to learn applications of the toolkit and the configuration file-based workflow.

Tasks involve:

• Create a yaml configuration file for the statistical model
• Replace the outdated methods from nsbi_common_utils library with the latest methods and workflows.
• Run the end-to-end workflow and update documentation.
