Pull Request Overview

This PR restructures the Visual Basic command-line compiler documentation by repositioning content and standardizing list formatting. The changes improve document flow by placing the introductory paragraph before the tip note and ensure consistent list numbering throughout.

Key changes:

• Moved the introductory paragraph to appear before the TIP note for better content flow.
• Standardized all ordered lists to use "1." for every item instead of sequential numbering (2., 3., 4., etc.).
