Bump ring to 0.17.3 to mitigate RUSTSEC-2025-0009

[MarkusPettersson98]

This PR bumps ring to version 0.17.13, which includes a mitigation for RUSTSEC-2025-0009.

We are not affected by this, since we do not encrypt/decrypt 64 gigabyte payloads:

ring::aead::quic::HeaderProtectionKey::new_mask() may panic when overflow checking is enabled.
In the QUIC protocol, an attacker can induce this panic by sending a specially-crafted packet.
Even unintentionally it is likely to occur in 1 out of every 2**32 packets sent and/or received.

On 64-bit targets operations using ring::aead::{AES_128_GCM, AES_256_GCM} may panic when 
overflow checking is enabled, when encrypting/decrypting approximately 68,719,476,700 bytes 
(about 64 gigabytes) of data in a single chunk.

Protocols like TLS and SSH are not affected by this because those protocols break large amounts 
of data into small chunks.  Similarly, most applications will not attempt to encrypt/decrypt 64GB 
of data in one chunk.
