What would you like to be added:
In the current parse_package_json.go, the expected structure to parse includes just the keyword author: https://github.com/anchore/syft/blob/main/syft/pkg/cataloger/javascript/parse_package_json.go#L24 . However, there are plenty of packages that use authors to register multiple authors.

Formats seen:

"authors": {
	   "Harry Potter <hp@hogwards.com> (http://youknowwho.com/) ",
	  "John Smith <j.smith[@something.com> (http://awebsite.com/) "
}

Or

"authors": {
	  "Harry Potter",
	  "John Smith"
}

An example package could be: https://github.com/Qix-/color/blob/master/package.json#L11

Why is this needed:

For more accuracy on parsing package.json structures.
