In a Bash task, declaring a volume binding overwrites default mount

[Melkaz]

Expected Behavior

Mounting /tmp to be accessible in a Bash task, executed in a container

id: test-volumes
namespace: io.kestra.flows.test
revision: 2
tasks:
  - id: task1
    type: io.kestra.core.tasks.scripts.Bash
    commands:
      - echo "Hello world 1" > /tmp/file1.txt
      - echo "Hello world 2" > {{ outputFiles['file2.txt'] }}
    dockerOptions:
      image: ubuntu:20.04
      volumes:
        - /tmp:/tmp
    outputFiles:
      - file2.txt
    runner: DOCKER
    
  - id: task2
    type: io.kestra.core.tasks.scripts.Bash
    commands:
      - cat /tmp/file1.txt
      - cat file2.txt
    dockerOptions:
      image: ubuntu:20.04
      volumes:
        - /tmp:/tmp
    inputFiles:
      file2.txt: "{{ outputs['task1'].outputFiles['file2.txt'] }}"
    runner: DOCKER
