Adds clarity to the associative list data type in wiremod (#73536)

## About The Pull Request

Once pulled, these changes will adjust how the associative list data
type is shown like on circuits and the description of the index table
component.

## Why It's Good For The Game

Given the entry difficulty level of the circuits system, some players
may find themselves overwhelmed and frustrated seeing that their index
table component's output is not connecting to the index list component's
input, despite there being an index associative list component they may
not be aware of. These changes should hopefully lead players to learn
more about associative lists and how different they are from normal
lists. Just adding "assoc." to the descriptor should lead players to
search the term in the component printer and find the index associative
table.
