Parent commands are not available in VS Code tasks

[l0rd]

Describe the bug

When a devfile uses a parent and the parent has some commands those are not visible as tasks in VS Code. This is probably due to the fact that the commands have the attribute controller.devfile.io/imported-by: parent in the flattened devfile:

- attributes:
    controller.devfile.io/imported-by: parent
  exec:
    commandLine: ./mvnw clean package -DskipTests=true
    component: tools
    group:
      isDefault: true
      kind: build
    label: 1. Package
  id: package

Che version

7.71@latest

Steps to reproduce

Start a workspace using the branch parent of this git repository: https://github.com/l0rd/inventory-quarkus/

Expected behavior

I would like to see the parents commands but I only see the ones coming from the devfile:

Now, the PR is updated and ready for review.
