Cargo deny advisory: proc-macro-error unmaintanied (https://rustsec.org/advisories/RUSTSEC-2024-0370)

[MaxCWhitehead]

We have this advisory triggering - (or perhaps will once iroh update is merged):

On this dep tree:

495 │ proc-macro-error 0.4.12 registry+https://github.com/rust-lang/crates.io-index
    │ ----------------------------------------------------------------------------- unmaintained advisory detected
    │
    = ID: RUSTSEC-2024-0370
    = Advisory: https://rustsec.org/advisories/RUSTSEC-2024-0370
    = proc-macro-error's maintainer seems to be unreachable, with no commits for 2 years, no releases pushed for 4 years, and no activity on the GitLab repo or response to email.

      proc-macro-error also depends on `syn 1.x`, which may be bringing duplicate dependencies into dependant build trees.

I disabled this advisory as it seems unlikely will be fixed upstream + iroh is also ignoring it - linked this issue in comment, closing for now to not clog up issue queue.
