To understand From-based conversion, an understanding of traits is required, which we teach in a later chapter. The From trait specifically is taught in one of the conversion exercises. So, we can safely remove it here without users missing out on learning something important. A specific source of confusion for users was a warning that the conversion is useless, which appeared when using the `string_slice` function for the expression with `.into()`. closes #2190
