While we typically use * instead of any, I just checked that these are interchangeable both by jsDoc standards and by the typescript conversion tool.

Though I'd argue that for consistency on the ref doc page itself, we should opt for * instead of any.

@ggetz updated to use *, please check again, I think it should be good to go
