citations: fix build
https://github.com/void-linux/void-packages/pull/43119

Description:
#### Testing the changes
- I tested the changes in this PR: **briefly**

Citations 0.5.1 has a specific commit hash for nom-bibtex in it's Cargo.lock, but nom-bibtex doesn't have that commit in it's master which causes cargo to fail. I solved it by updating the commit to an equivalent commit which is in master, but it has a different hash probably because it's based on nom-bibtex 0.4.0 instead of 0.3.0.
