Fix citation author name issue (#19597)

Use `name` rather than `given-names` to set author name.

### Motivation and Context
The old CITATION.cff uses `given-names` to set author names, which won't
be rendered properly with some bibtex style of LaTeX:

The problem is that **the `"ONNX Runtime developers"` is regarded as a
human name**.

How to fix: by using `name` to set author name, the generated Bibtex
entry will use `{}` to enclose the `"ONNX Runtime developers"`. Then it
is displayed literally:
