Issue Description

At out pipeline, we are using trivy@1 task for security-scanning our container images from our private ACR.
Recently the task started to be failed without any changes on our side:

2025-05-07T00:12:40Z FATAL Fatal error image scan error: scan error: unable to initialize a scan service: unable to initialize an image scan service: unable to find the specified image "***/xxxxx:develop" in ["docker" "containerd" "podman" "remote"]: 4 errors occurred:
* docker error: unable to inspect the image (***/xxxxx:develop): Error response from daemon: No such image: ***/xxxxx:develop
* containerd error: containerd socket not found: /run/containerd/containerd.sock
* podman error: unable to initialize Podman client: no podman socket found: stat podman/podman.sock: no such file or directory

Our original pipeline configuration looks like

          - task: Docker@2
            displayName: Login to ACR
            inputs:
              command: login
              containerRegistry: xxxxxxxxxx
          - task: trivy@1
            displayName: Image Scan
            inputs:
              image: xxxxxxxxxxxxx/xxxxx:develop
              loginDockerConfig: true

From the above error message, Docker@2 login doesn't seem to work and we have replaced task: Docker@2 with the following script task.

          - script: |
              docker login -u "${ACR_TOKEN_NAME}" -p "${ACR_TOKEN_PASSWD}" "${ACR}"
            displayName: Login to ACR with docker

This change works for our task: trivy@1, but I still have a question this is expected.
