## Summary
Updates the `spdx` dependency from 0.12.x to the latest release, 0.13.2.
https://github.com/EmbarkStudios/spdx/blob/0.13.2/CHANGELOG.md
Here in uv upstream, this just helps keep dependencies up to date; there
isn’t any other particular specific motivation or benefit. Downstream in
Fedora, this change allows me to avoid maintaining a `rust-spdx0.12`
compat package.
