Autorenew abyss skull

What has been done in this MR?

• The Abyss skull is now automatically renewed whenever the player enters the abyss, as opposed to its current behavior of expiring 20 minutes after the first time the player enters the abyss.

What should testers check?

• Enter the abyss at time X. Enter the abyss again at a later time, say Y=10 minutes. Observe that you now become unskulled at X+Y+20 minutes, rather than at X+20 minutes.

• I have tested these changes thoroughly.

• I used the relevant Thanos/Zaros tool for any JSON edits where possible, and have attached screenshots of any changes.
