html: XSS via Incorrect Handling of Character References in DOCTYPE

This CVE does not affect KrakenD

KrakenD is an API gateway and does not use golang.org/x/net/html to parse or render HTML content from user requests. The vulnerable HTML parsing code path is never invoked during KrakenD operation.

Addressed through routine dependency maintenance in CE 2.13.6 and EE 2.13.4.
