this is not a safe assumption; i.e. the $ref could be a reference to a schema in another file, such as
$ref: '../components.yaml/#/components/schemas/foo' in which case fetching schemas[propertyName] may fail or may fetch the wrong schema.
This tool does not resolve external references; see the README which says
"The tool only supports self-contained documents. It does not follow or resolve external $ref documents embedded in the source document."
See https://github.com/apiture/api-ref-resolver for tooling to supports resolving external $ref references before down converting. (However this tool should not assume that all external $ref have been resolved)
So instead, I suggest either checking that the $ref starts with '#/components/schemasor after splitting on '/' thatcomponents[0] === '#' && components[1] === 'components' && components[2] === 'schemas'`

this would be cleaner with
const isNullable = entries.find( (v) => .... );

I'd like to see a test where the schema d has an allOf referencing a , so that d is also tagged as nullable,
or a schema e that has an allOf with type f where f has type: [string, 'null'] so that both f and e are marked nullable

Resolves #23 - I ended up finding some time this weekend to work on this.
This change allows for the conversion of anyOf/oneOf arrays with $ref/obj and a
type: "null", which is a common way to do a type union in 3.1.0 to allow for a type to be a $ref, but also nullable. I've tested it on my own rather beefy spec (250+ endpoints and hundreds of types) with zero changes and it passed typecheck. I recently upgraded my spec to 3.1.0 and the conversion tools used by this project were not able to accurately convert the 3.1.0 spec.Hopefully this is a good enough addition to add, it certainly suits my purposes. I can understand if it should be behind a flag though. Let me know if there are any other situations I may have missed.
Thanks!
