Purpose

Per Slack conversation, team finished a round of internal checking on nodes missing help content. In this PR, I am adding back missing dyns that I could validate which were missing.

Also fixed image display for the following nodes:

• DSCore.Math.Random(value1, value2, seed)
• DSCore.Math.RandomList(amount, value1, value2, seed)
• DSCore.Math.Abs(number)
• DynamoUnits.Quantity.ByTypeID

Added copy step for excel sheets in help docs

• CoreNodeModels.Input.CustomSelection.dyn added by @twastvedt It looks like the dyn file was missing from original PR: AGD-2199 - custom dropdown node #11958)

Node with issue

• OpenXML nodes, excel sheets will always come with path problem
