Uneven Dream - Reimplement the Pretty Powerlines badge once Rainy Garden comes back in a future update

A file with this content would need to be readded at `badges/unevendream/rainy_garden_powerline.json`:
```
{
  "bp": 10,
  "reqType": "tag",
  "reqString": "rainy_garden_powerline",
  "map": 58,
  "art": "Olive Deer",
  "batch": 26
}
```

The conditions and lang entries may also have to be edited, though those ones were not removed.
