Subject: [PATCH] build(deps): Upgrade to ed25519-zebra 4.0.0 (#6881)

* build: Upgrade to ed5519-zebra 4.0.0

* skip-tree hashbrown =0.13.2 because ed25519-zebra is 0.14.0 and a dep of metrics-exporter-prometheus is 0.13.2

* Use correct versions in deny.toml

* Oops turns out we need both exceptions
