-  Modify Docker build step to tag images using PR number only
-  Add a new step to retrieve Docker image information using docker inspect and jq
-  Add another step to post this Docker image information as a comment on the PR using actions/github-script
-  The image information includes the image ID, creation time, size, and tags
