I disabled the 3 core moderation modules that are enabled by default now in Lightning: Content Moderation, Workflows, Lightning Workflow, and Scheduler.
I installed what we are using for moderation: Workbench 8.x-1.0, and Workbench moderation 8.x-1.3.
I created 1 node and published it. I went to My Workbench and I see 1 node published.
I enabled all 4 core translation modules:

I went to the first node and added a translated version of it. And saved it
as a draft.I went to My Workbench and I see 5 items. 4 are the original node
and 1 is the translated node. All 5 items link to the original node. If I
publish the translated version of the node, then Workbench displays 5 items
that are all the translated version and all 5 link to the translated
