build(deps): Upgrade ECC dependencies

[oxarbitrage]

Motivation

We need to upgrade the ECC dependencies for NU6.

Close #8749
Close #8799

Solution

We can upgrade the root Cargo.toml which makes this a lot easier (thank you @tomekpiotrowski !).

However, we need to remain in older versions for some of the ECC crates in the zebra-scan crate for now.

Tests

CI should take care of this.

Thank you!

Looks like we need to update the deny.toml here as well.
