The citation file cannot be parsed about agda-unimath

This is due to the fact that .cff is a .yaml based format, and should not be formatted as a BibTeX reference.

Here's a sample corrected CITATION.cff file:

cff-version: 1.2.0
message: "If you use this software, please cite it as below."
authors:
  - family-names: "Rijke"
    given-names: "Egbert"
  - family-names: "Bonnevier"

  - family-names: "Prieto-Cubides"

title: "Univalent mathematics in Agda"
abstract: "The agda-unimath library is a community formalisation project for univalent mathematics in Agda. Our goal is to formalize an extensive curriculum of mathematics from the univalent point of view. Furthermore, we think libraries of formalized mathematics have the potential to be useful, and informative resources for mathematicians. Our library is designed to work towards this goal, and we welcome contributions to the library about any topic in mathematics."

url: "https://unimath.github.io/agda-unimath/"
keywords:
  - type-theory
  - homotopy-type-theory
  - univalent-foundations

GitHub can then compile this information to generate a BibTeX reference.

I'm not sure "others" should be cited as an author though. It's also possible to add personal links for each author.
