cargo-deny has MSRV 1.74, which is inconvenient since zcashd has 1.69.0 in rust-toolchain.toml

[daira]

This requires something like:

cargo +1.74 install cargo-deny
cargo +1.74 deny check

This also outputs a bunch of warning[index-failure]: unable to check for yanked crates warnings, which I think is indirectly due to the same issue: cargo +1.74 deny check cannot find the cache of crates that were built for zcashd.
