Title: Fix Overlapping Text Issue on SBOM Diagram for Better Readability

### Current Behavior

**Description:**
The text on the dependancy track diagram overlaps the image elements, making it difficult to read and affecting the clarity of the information.

### Proposed Behavior

**Proposed Solutions:**
- Utilize Text Backgrounds: Apply semi-transparent background boxes behind the text to prevent blending with the image and ensure the text remains legible.
- Dropdown repositioning: Repositioning the text a little closer to the image and make the text open upwards.
