[MC-218039] "Empty range decorator" spam in logs when creating a custom world

When creating the following custom dimension via a datapack:

'data/foo/dimension/custom.json' : 
{
  "generator": {
    "biome_source": {
      "large_biomes": false,
      "seed": 0,
      "type": "minecraft:vanilla_layered"
    },
    "seed": 0,
    "settings": "minecraft:nether",
    "type": "minecraft:noise"
  },
  "type": "minecraft:the_end"
}

the following errors tend to spam the system logs:

Empty range decorator: RangeDecorator@2d4e6bb2 [136-127]
Empty range decorator: RangeDecorator@2d4e6bb2 [136-127]
Empty range decorator: RangeDecorator@2d4e6bb2 [0--8]
Empty range decorator: RangeDecorator@2d4e6bb2 [0--8]
Empty range decorator: RangeDecorator@2d4e6bb2 [0–8]

suggesting calming down on the error messages due to now modifiable world Y limits.
