Subject: [PATCH] Remove Notable Traits section from definitions

Rust 1.47.0 introduced the Notable Traits section that lists information
about types used in code block.  As we only want to display the code
block itself without meta-information, this patch ignores the
notable-traits class when extracting the text from nodes.
