Set values coming from OTEL_NODE_RESOURCE_DETECTORS when using config file

[maryliag]

The values coming from OTEL_NODE_RESOURCE_DETECTORS should be set into the configModel, probably using something like

"ExperimentalResourceDetection": {
            "type": "object",
            "additionalProperties": false,
            "properties": {
                "attributes": {
                    "$ref": "common.json#/$defs/IncludeExclude"
                },
                "detectors": {
                    "type": "array",
                    "items": {
                        "$ref": "#/$defs/ExperimentalResourceDetector"
                    }
                }
            }
        },

      #  * If the value of the attribute key exactly matches.
      #  * If the value of the attribute key matches the wildcard pattern, where '?' matches any single character and '*' matches any number of characters including none.
      # If omitted, all attributes are included.
