Add Stage&Context Scan for SBOM #3263
Description
Describe the issue
The current Docker image lacks meaningful information for the SBOM due to its single-binary distroless image. Therefore, we believe additional analysis should be pursued by adding SBOM options (BUILDKIT_SBOM_SCAN_CONTEXT, BUILDKIT_SBOM_SCAN_STAGE).
