Subject: [PATCH] Fix use of unmaintaned crate proc-macro-error, by replacing
 it with the maintained proc-macro-error2 crate (#627)

# Objective

The Avian macro crate uses `proc-macro-error`, which is [unmaintained](https://rustsec.org/advisories/RUSTSEC-2024-0370), this also leads to an outdated version of `syn` in the dependency tree.

## Solution

Replace `proc-macro-error` with `proc-macro-error2`.
