Create a reusable DockerfileLayer component for rendering individual Dockerfile layers with conditional bold styling.

Implementation Details:

• Create DockerfileLayer.tsx component
• Props: {{ { layer: TableDataRow['layer']; isBold?: boolean; }

  }}

• Render layer instruction and value in code block format
• Apply pf-v5-u-font-weight-bold class when isBold === true
• Use PatternFly code block styling for consistent appearance
• Show fallback message if layer data is unavailable
• Handle edge cases (missing instruction, missing value)

Acceptance Criteria:

• Renders layer instruction (e.g., "FROM", "RUN", "COPY") correctly
• Renders layer value correctly
• Applies bold styling when isBold prop is true
• Normal styling when isBold is false or undefined
• Handles missing layer data gracefully with fallback message
• Uses consistent code block formatting
