New Model Grouping hides all non-default quants from the api

[jmaver]

I was previously able to pick what I wanted for any model/quant using the list of returned downloaded models, but after this update, I now only get the default single quantization with no way to see the others.

Ex: I downloaded 3 quants for granite-4-h

lms ls and the python sdk basically return this, with just the first mondel

{
    "type": "llm",
    "modelKey": "ibm/granite-4-h-tiny",
    "format": "gguf",
    "displayName": "Granite 4 H Tiny",
    "publisher": "ibm",
    "path": "ibm/granite-4-h-tiny",
    "sizeBytes": 4231029813,
    "paramsString": "7B",
    "architecture": "granitehybrid",
    "quantization": {
      "name": "Q4_K_M",
      "bits": 4
    },
    "vision": false,
    "trainedForToolUse": true,
    "maxContextLength": 1048576
  },

How do I programmatically get to know about the other quants and load them?
