Adds notice-span to visible_messages with no spans (#46044)

About The Pull Request

Adds 'notice' span class to all visible_messages which had no span class, making all those black messages blue.
Why It's Good For The Game

This should help differentiate action-messages from talking-messages in the chat. More actions will be blue, thus black talking-messages should pop out more.
