Fix cargo deny warnings (#808)

This changeset fixes the `cargo deny` warnings:

- Updated rustls-webpki 0.103.10 -> 0.103.13 (fixes the advisories for
this copy)
- Updated bitstream-io 4.9.0 -> 4.10.0 (removes yanked core2)
- Ignored RUSTSEC-2026-0098, 0099, 0104 in deny.toml — the rustls-webpki
0.101.7 (from aws-smithy-http-client) and 0.102.8 (from dropshot) copies
are locked by upstream crates with no newer versions available
