And updates all the links so they point to the RFC.

interestingly, having simpler test vectors like this in the spec could be beneficial. It's not going to be for this protocol as it's already RFC, but I sense it would be quite useful to have a test vector that fits in a simple example.

### GitHub Vulnerability Alerts

####
[GHSA-9763-4f94-gfch](https://togithub.com/cloudflare/circl/security/advisories/GHSA-9763-4f94-gfch)

### Impact
On some platforms, when an attacker can time decapsulation of Kyber on
forged cipher texts, they could possibly learn (parts of) the secret
key.

Does not apply to ephemeral usage, such as when used in the regular way
in TLS.

### Patches
Patched in 1.3.7.
