Did you check that we are not losing any valuable information and that the conclusion contained only summaries/recaps?

Second, there is no need to duplicate this for the versioned v4 docs, we have a CI pipeline that handles the copying. Please remove the duplication.

@vdusek, I did check what I'm deleting from docs, no worries. Conclusions didn't carry any valuable information.
