Fix a follow up issue to move back with [Linkit] module from ~5.0 to ~4.0

After #3101505: Update [Linkit] module from ~4.0 to ~5.0
A needed change for linkit, as the button had been removed.
And an activation for the DrupalLink core link with

  plugins:
    drupallink:
      linkit_enabled: true
      linkit_profile: linkit_all_nodes

          name: Linking
          items:
            - DrupalLink
            - DrupalUnlink
            - Anchor

          name: Linking
          items:
            - '-'
            - Linkit
            - '-'
            - Link
            - Unlink
            - '-'

  linkit:
    id: linkit
    provider: linkit
    status: true
    weight: 0
    settings:
      title: true
  token_filter:
    id: token_filter
    provider: token_filter
    status: false
    weight: 0
    settings:
      replace_empty: '0'

This update could go into a new branch with a smooth update process

So going back to the old config for linkit ~4.0
