Error when Importing DTDLs generated in IoT Central using ADT Explorer, CLI works fine

The dtdls are simple, created in Azure IoT Central and export directly, showed below:
```
[
{
"@id": "dtmi:dtdlv2:TempSensor:original;1",
"@type": "Interface",
"contents": [
{
"@id": "dtmi:dtdlv2:TempSensor:Temperature;1",
"@type": [
"Property",
"Temperature"
],
"displayName": {
"en": "Temperature"
},
"name": "Temperature",
"schema": "double",
"unit": "degreeCelsius",
"writable": true
},
{
"@id": "dtmi:dtdlv2:TempSensor:Humidity;1",
"@type": [
"Property",
"RelativeHumidity"
],
"displayName": {
"en": "Humidity"
},
"name": "Humidity",
"schema": "double",
"unit": "percent",
"writable": true
}
],
"displayName": {
"en": "TempSensor"
},
"@context": [
"dtmi:iotcentral:context;2",
"dtmi:dtdl:context;2"
]
}
]
```
Following errors will pop up when import using ADT Explorer:
>DocumentParseError: Failed to parse input. Error: jsonld.InvalidUrl: Dereferencing a URL did not result in a valid JSON-LD object. Possible causes are an inaccessible URL perhaps due to a same-origin policy (ensure the server uses CORS if you are using client-side JavaScript), too many redirects, a non-JSON response, or more than one HTTP Link Header was provided for a remote context.

Need to remove `"dtmi:iotcentral:context;2"` from `"@context"` in order to perform a successfully import using ADT Explorer.

OR using CLI, the import will success without editing the original file.
