input: Write a function to convert a list of strings to floats using the float() function.
  assert convert_to_floats(["12.45", "0.99", "8.67"]) == [12.45, 0.99, 8.67]
  assert convert_to_floats(["1.0", "2.5", "3.14"]) == [1.0, 2.5, 3.14]
  assert convert_to_floats(["10", "20.5", "30.33"]) == [10.0, 20.5, 30.33]
output: def convert_to_floats(string_list):
      return [float(s) for s in string_list]
