Wormholes no longer decay when used (#3292)

## About The Pull Request

Wormholes are now permanent if one spawns on the overmap, rather than
being usable a few times then deleting themselves. Ideally this will
make them slightly more interactable in the event they help transit
enough

## Why It's Good For The Game

I don't feel like wormholes being usable maybe up to 5 times makes them
particularly more interesting than not, since there's no reason to check
what is on the other side if you won't be able to use it for more than 2
round trips in the best case

your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
