docs: // getTaskIDfromARN parses a task ARN and produces the task ID
  // A task ARN has format arn:aws:ecs:[region]:[account-id]:task/[task-id]
  // For a correctly formatted ARN we split it over ":" into 6 parts, the last part
  // containing the task-id which we extract by splitting it by "/".
  // This function should be eventually be replaced by a standardized ARN parsing
