A few reference-related renamings

[alexdewar]

Noticed this while I was working on something else... The function is called get_reference even though it returns multiple references. And the file is called references.py (plural) when we've used singular names for the other files (e.g. section.py). Fix this.

Consider updating the docstring to clarify that the function returns a single structured reference or adjust the function name if multiple references are expected.

def get_references(reference: dict[str, Any], section_heading: str) -> dict[str, Any]:
