update dependencies (#4639)

## Issue Addressed

updates underlying dependencies and removes the ignored `RUSTSEC`'s for `cargo audit`.

Also switches `procinfo` to `procfs` on `eth2` to remove the `nom` warning, `procinfo` is unmaintained see [here](https://github.com/danburkert/procinfo-rs/issues/46).
