Bump hermit-abi & num_cpus packages (#5427)

## Problem

I've noticed that `hermit-abi`
0.3.1 [1] has been yanked from crates.io (looks like nothing too
bad [2]).
Also, we have 2 versions of `hermit-api` in dependencies (0.3.* and
0.2.*), update `num-cpus` to use the latest `hermit-api` 0.3.3.

- [1] https://crates.io/crates/hermit-abi/0.3.1
- [2] https://github.com/hermit-os/hermit-rs/issues/436

## Summary of changes
- `cargo update -p num-cpus`
- `cargo update -p hermit-abi`
- Unignore `RUSTSEC-2023-0052` in `deny.toml` (it has been fixed in
https://github.com/neondatabase/neon/pull/5069)
