Add Makefile Configuration Page to Data Handbook

[simonprydden]

User Story:

As a data engineer,
I want a dedicated page in the data handbook outlining recommended Makefile configurations for data projects,
so that I can quickly and consistently set up build and automation processes for new data projects, reducing setup time and ensuring adherence to best practices.

Acceptance Criteria:

• A new page titled "Makefile Configuration" is added to the data handbook.
• The page includes a clear explanation of what a Makefile is and its purpose in data projects.
• The page provides a sample Makefile configuration with comments, demonstrating common tasks such as:
  • Setting up virtual environments.
  • Installing project dependencies.
  • Running tests.
• The page includes recommendations on best practices for organizing and structuring Makefiles.
• The sample configuration is tested and confirmed to be functional.
• The page is easily accessible and searchable within the data handbook.
