I upvoted a question, it later got closed as a duplicate so I wanted to undo my vote and it was locked.
Shouldn't the insertion of that content count as an edit? Or even the act of being closed (as whatever reason)?

No, it should not be considered an edit. Edits are for when users have changed the content. When a "duplicate entry" tag is added, it is a note to other users, but the content was still not edited by some user.
This also affects whether or not it turns into CW.
But there is really no advantage to have it count as an edit, except to people who want to change their votes. But votes should be based on the question and not the general context.
If you feel that strongly about it, just manually do a null edit, and remove your upvote.
