Includes a fix for CVE-2023-45288, which is also addressed in go1.22.2
and go1.21.9;

> http2: close connections when receiving too many headers
>
> Maintaining HPACK state requires that we parse and process
> all HEADERS and CONTINUATION frames on a connection.
> When a request's headers exceed MaxHeaderBytes, we don't
> allocate memory to store the excess headers but we do
> parse them. This permits an attacker to cause an HTTP/2
> endpoint to read arbitrary amounts of data, all associated
> with a request which is going to be rejected.
>
> Set a limit on the amount of excess header frames we
> will process before closing a connection.
>
> Thanks to Bartek Nowotarski for reporting this issue.
