Che-docs devfile is out-of-date with repo

[amisevsk]

Describe the bug

The devfile in the che-docs repo contains the default command

  - exec:
      commandLine: bash tools/newtopic.sh
      component: tools
      label: Create a new topic
      workingDir: "${PROJECT_SOURCE}"
    id: create-a-new-topic

which is used to create a new topic. The tools/newtopic.sh script uses newdoc to create the actual file, but since https://github.com/eclipse-che/che-docs/pull/2370 the newdoc binary is no longer available in the quay.io/eclipse/che-docs:next image, causing that command to fail.

Che version

next (development version)

Steps to reproduce

1. Start a workspace using the che-docs URL: https://github.com/eclipse-che/che-docs.git
2. Attempt to run the create-a-new-topic command

Expected behavior

An alternative way to allow users to create docs should be provided.
