Update some packages realated to ring and aws-lc

[LecrisUT]

After aws-lc-rs 0.15 it seems the illumos issue is resolved, so reviving the metrics et.al. update PR, specifically:

• Update metrics to 0.24 and metrics-exporter-prometheus to 0.17
• Drop the ring feature from rustls
• Update reqwest to 0.12 (dropping rustls 0.21 from the lock file)

There still seem to be ring dependencies, but not sure if these can be dropped

[LecrisUT]

Well, the ring dependency is still hard-coded here

atuin/crates/atuin-server/src/lib.rs

Line 82 in 888c098

let crypto_provider = rustls::crypto::ring::default_provider().install_default();

so "completely dropping" ring (will always have dependency due to rusty_paseto?) is still not possible. But for now, just unblocking metrics with this would be great 🙏
