Expose remote_table option in Native Queries Relationships UI

[cpouldev]

Reading the native queries docs , at the part of relationships with table it shows the ability to map a table to a logical model's column via the remote_table option:

 {
      "type": "pg_track_native_query",
      "args": {
        "arguments": {},
        "array_relationships": [],
        "code": "SELECT * FROM (VALUES (1, 'Logical Models', 1), (2, 'Native Queries', 2), (3, 'Relationships', 3), (4, 'Graph Relationships', 4), (5, 'Permissions', 5)) as t(\"id\", \"title\", \"author_id\")",
        "object_relationships": [
          {
            "name": "author",
            "using": {
              "column_mapping": {
                "author_id": "id"
              },
              "insertion_order": null,
              "remote_table": "authors" <------ HERE
            }
          }
        ],
        "returns": "article",
        "root_field_name": "get_articles",
        "source": "default",
        "type": "query"
      }
}

this option is missing on the UI
