Render code blocks with syntax highlighting

[dns2utf8]

Thank you for the cool feature.
I noticed that it currently does not render rust code with highlighting.

In one of my crates I have a code example with a ´```rust´ block.
Can you extend it to highlight the code?

Best regards

We had to disable syntax highlighting temporarily for security reasons-- #1008 we're waiting on the next Ammonia crate release to re-enable.

I'm going to close this as a duplicate of #1008 :)

Works for me. Thank you.
