[Bug] Info format is hardcoded to default value causing getFeatureInfoText to fail

[kolpav]

Description

I couldn't get feature info request to work because current implementation hard codes INFO_FORMAT value.

deck.gl/modules/geo-layers/src/wms-layer/wms-layer.ts

Line 152 in 29980be

info_format: 'application/vnd.ogc.gml'

I think it should take value returned from service when calling GetCapabilities

"requests": {
    "GetFeatureInfo": {
      "mimeTypes": [
        "text/html"
      ]
    }
  }

I am very new to WMS and other mapping technologies so I might be doing something wrong.

Steps to Reproduce

Call getFeatureInfoText on service not supporting application/vnd.ogc.gml
