bug: Erroneous comment in Drop's TempFile inverts order of destruction

[AlanDeSmet]

In the page on Drop (https://doc.rust-lang.org/rust-by-example/trait/drop.html ), the TempFile example includes the following:

// When TempFile is dropped:
// 1. First, the File will be automatically closed (Drop for File)
// 2. Then our drop implementation will remove the file
impl Drop for TempFile {
    fn drop(&mut self) {
        // Note: File is already closed at this point
        if let Err(e) = std::fs::remove_file(&self.path) {

I believe the comments are incorrect. I believe TempFile::drop is called before File::drop, so the file is still open when std::fs::remove_file is called.

As an additional issue, removing the file while it's still open is fine on Unix-like operating systems, but may cause problems on Windows or other operating systems that block removing opened files.
