main/cargo-auditable: upgrade to 0.6.5
Not sure if it's already too late for Alpine 3.21, but this adds support for the upcoming Rust 2024 Edition.
I can also backport this change to cargo-auditable 0.6.4 if needed.

If that's difficult to get packaged at this stage, you can simply apply the patch in this PR (changing 0.15 to 0.18) on the distro level.
