Subject: [PATCH] Restore original meaning of std::fs::read_dir's example
 changed in #33958.

DirEntry.file_type().is_dir() will not follow symlinks, but the original
example (fs::metadata(&path).is_dir()) does. Therefore the change in
#33958 introduced a subtle difference that now it won't enter linked
folders. To preserve the same behavior, we use Path::is_dir() instead,
which does follow symlink.
