vendor: golang.org/x/net v0.4.0

golang.org/x/net contains a fix for CVE-2022-41717, which was addressed
in stdlib in go1.19.4 and go1.18.9;

> net/http: limit canonical header cache by bytes, not entries
>
> An attacker can cause excessive memory growth in a Go server accepting
> HTTP/2 requests.
>
> HTTP/2 server connections contain a cache of HTTP header keys sent by
> the client. While the total number of entries in this cache is capped,
> an attacker sending very large keys can cause the server to allocate
> approximately 64 MiB per open connection.
>
> This issue is also fixed in golang.org/x/net/http2 v0.4.0,
> for users manually configuring HTTP/2.
