rustdoc: fix treatment of backslash-escaped HTML

Try generating HTML for this markup:

    \<a href="https://example.com">example</a>

It will produce text, not HTML, in both rustdoc's real HTML output and in
the commonmark reference implementation:

https://spec.commonmark.org/dingus/?text=%5C%3Ca%20href%3D%22https%3A%2F%2Fexample.com%22%3Eexample%3C%2Fa%3E
