Reports unknown properties in blocks

Example of a problem:


resource "awscc_appflow_flow" "aws_flow1" {
  flow_name          = ""
  source_flow_config = ""
  trigger_config     = ""
  destination_flow_config_list {}
  tasks {}
  test = ""
}

In this example, the test property in the block is unknown.

Example of correction:


resource "awscc_appflow_flow" "aws_flow1" {
  flow_name          = ""
  source_flow_config = ""
  trigger_config     = ""
  destination_flow_config_list {}
  tasks {}
}
