Update markdown-it version

Fixes improperly-escaped pipes in Markdown tables for the [documentation of bad_bit_mask](https://rust-lang.github.io/rust-clippy/master/index.html#bad_bit_mask) and [ineffective_bit_mask](https://rust-lang.github.io/rust-clippy/master/index.html#ineffective_bit_mask). A column pipe takes precedence over inline code markers, so some back ticks are displayed literally and the pipes need to be escaped. I found no other occurrences of the same problem when searching rust-clippy by ```\|.*`.*\|```.
