Workspace startup fails when the Devfile specifies cpuRequest or cpuLimit and the editor is VS Code

schemaVersion: 2.1.0
metadata:
  name: java-guestbook
components:
  - name: tools
    container:
      image: quay.io/devfile/universal-developer-image:ubi8-0e189d9
      cpuLimit: '1'

Using a Devfile such as the one above and using the URL parameter `che-editor=che-incubator/che-code/insiders` the following error is returned (c.f. the screenshot attached to the issue):

Getting workspace detail data failed. Failed to start the workspace java-guestbook, reason: 1 error occurred: * error parsing cpuLimit requirement for component tools: quantities must match the regular expression '^([+-]?[0-9.]+)([eEinumkKMGTP]*[-+]?[0-9]*)$'

This issue is related to che-code DevWorkspace Handler and can be fixed there but the devworkspace handlers are supposed to be retired with the introduction of DevWorkspaces' containersContributions.

Rather than fixing che-code DevWorkspace Handler we are going to stop using it in the Dashboard and add containersContributions in the IDE definitions in the plugin registry.

UPDATE: this issue has been addressed upstream before the introduction of containersContributions
