[BUG][csharp-netcore] bearerAuth is interpreted as basicAuth

Created by: FaFre

Description

I added a bearer authentication in my description according to the the swagger docs:

"components": {
    "securitySchemes": {
      "bearerAuth": {
        "type": "http",
        "scheme": "bearer",
        "bearerFormat": "JWT"
      }
    }
...
"security": [
    {
      "bearerAuth": []
    }
  ]

But for some reasons the generated code contains an basicAuth with username/password instead of the bearer expected as Authorization: Bearer <token>:

DefaultApi.cs:

// authentication (bearerAuth) required
            // http basic authentication required
            if (!String.IsNullOrEmpty(this.Configuration.Username) || !String.IsNullOrEmpty(this.Configuration.Password))
            {
                localVarRequestOptions.HeaderParameters.Add("Authorization", "Basic " + Org.OpenAPITools.Client.ClientUtils.Base64Encode(this.Configuration.Username + ":" + this.Configuration.Password));
            }
