Logic to set Auto Accepted Translations Publication Status (accordingly to the Source)

Problem/Motivation

This recent major task Support pending revisions and accepting translation as a specific moderation state introduced a logic to Review and Save the incoming Job Item / Translation matching as default the Source Translation Status: if it is Published the "Save and Accepted" would Default set the new Translation Moderation State to it, leaving the user able to modify/customise.
This choice is managed by the "#moderation_state" that is set in the job Item data to carry the information about the new moderation state value (see here).

The $data['#moderation_state'] is then used to set the proper moderation state for the Translation (see here).

At the moment, in case of Auto Accepted Job Items, the $data['#moderation_state'] is undefined so as also could be the $data['#published'], thus the Translations are automatically saved matching their original status, causing weird and un-expected outcomes in Basic and more Advanced use case, such for instance the following:
- if the Translation Source is Published but the Auto Accepted is not, then the new Accepted Translation is being save as Un-Published, and setting as Un-Published also the Translation Source, hence breaking the Auto Accept flow of subsequent incoming/remaining Languages Translations

Proposed resolution

In case of Auto Accepted Translation/$data['#moderation_state'] undefined, define it accordingly of the Moderation State of the Source Entity (if Moderated), so to let the Translation publication state being saved accordingly ...
