Same commit and PR links are used for every items in a release note

[rhysd]

Hi, wry crate is using covector and I noticed the release notes generated by covector seemed wrong.

https://github.com/tauri-apps/wry/releases

Screenshot of example:

All items in a single release have the same commit and PR links wrongly (8646120 and #1159 in the screenshot). FWIW, the first time I saw this issue was the release of wry v35.0 (published on Nov 21, 2023): https://github.com/tauri-apps/wry/pull/1054

The workflow is here: https://github.com/tauri-apps/wry/blob/dev/.github/workflows/covector-version-or-publish.yml
