It might be better to grab this from the update checker

Though I don't think the update checker currently records this for GitHub, so a TODO comment would suffice for now

Wouldn't using releases/latest (like it is currently) suffice for this? I don't see the difference it would make.

I just mean that the update checker might not always point to GitHub (e.g. in the future it could recommend Spigot if that's where you downloaded Skript from)

It might be worth integrating this into the ReleaseStatus enum
