The most significant changes include clarifying deployment instructions, updating the naming and formatting in the documentation, and ensuring resource group tags are merged correctly in the infrastructure templates.

Documentation improvements:

• Updated the deployment instructions to clarify the use of VS Code Dev Containers and Git Bash for running sample data scripts, making the process more user-friendly and accurate. [1] [2]
• Improved the formatting and clarity of the configurable deployment settings section, removing the markdown table and fixing the link to customization instructions.
