input: Write a function to create a web scraper in Python that can extract hotel reviews from TripAdvisor given a URL. The function should use the `requests` library to make a request with a specific `User-Agent` header, parse the HTML with `BeautifulSoup`, and extract the title and text of each review from the `div` elements with class `review-container`. The function should print the title and text of each review followed by a line of dashes.
  assert scrape_hotel_reviews('<url>')==None
  assert type(scrape_hotel_reviews) == type(lambda: None)

      response = requests.get(url, headers=headers)
      soup = BeautifulSoup(response.text, 'html.parser')
