WorldEdit can't find snapshots of world with custom dimensions

**Versions**
WorldEdit version: 7.2.0, build 5280
Platform version: Fabric 0.9.1

**Describe the bug**
WorldEdit can't find snapshots of world with custom dimensions (feature from 1.16)

**To Reproduce**
1) Create a backup of world (using zip command from docs or 7-zip)
2) /snap list
3) As a result we get "WorldEdit found no snapshots: looked in: D:\MyGames\MinecraftServer\temp\backups"

**Expected behavior**
List of snapshot

**Notes**
1) I used world from first attached file, which has been generated from config in second file.
2) If delete backup and world folder without changing config WorldEdit can see backups of new (not custom) world.
