Change proc-macro-error to proc-macro-error2 to fix https://rustsec.org/advisories/RUSTSEC-2024-0370

Hello.

cargo-deny detects the security issue in this crate.

• issue: https://rustsec.org/advisories/RUSTSEC-2024-0370

So I change proc-macro-error to proc-macro-error2 to fix it. I chose proc-macro-error2 because the interface is unchanged.

Please let me know if there is something I should do.

Thanks.

Ah, that's what I get for not opening an issue for myself, completely forgot about fixing that.

Please drop the crate version changes as those will be updated when the release is tagged.
