Subject: [PATCH] rustdoc: clean up sidebar.html block class

This line is longer than 100 characters, but apparently,
[tidy's list of checked extensions] doesn't include html,
so the line length doesn't matter.

[tidy's list of checked extensions]: https://github.com/rust-lang/rust/blob/31be8cc41148983e742fea8f559aacca0f6647db/src/tools/tidy/src/style.rs#L245
