Scanning for dependencies fail when building using docker BUILDKIT

[mnltejaswini]

Describe the bug When building with DOCKER_BUILDKIT=1, the build fails to scan dependencies with the following error

failed to query digests, msg:
Error: No such object: mcr.microsoft.com/dotnet/sdk:3.1
: exit status 1

To Reproduce Steps to reproduce the behavior:

1. create a simple Dockerfile Sample Dockerfile

   FROM mcr.microsoft.com/dotnet/sdk:3.1

2. create a task file to build that docker file with BUILDKIT enabled

   version: v1.1.0
   steps:
   - id: build
   build: -t $Registry/test:$ID -f Dockerfile .
   env: ["DOCKER_BUILDKIT=1"]

3. The build fails to scan dependencies.

   Error: No such object: mcr.microsoft.com/dotnet/sdk:3.1
   : exit status 1 

Expected behavior The build should be success and provide dependencies. Screenshots If applicable, add screenshots to help explain your problem.
