Update to latest cargo deny release

[konstin]

The cargo deny part of precommit is failing for me locally since it assumes an older version of cargo deny than the latest release. We should upgrade to the latest cargo deny.

$ uvx pre-commit run --hook-stage manual --all
cargo fmt................................................................Passed
cargo deny...............................................................Failed
- hook id: cargo-deny
- exit code: 1
