IncomingRequestCfProperties is not matching the definition described in docs

[motiejunas]

What is the source of truth for IncomingRequestCfProperties interface? Docs or the type defined by @cloudflare/workers-types? One or the other should be adjusted.

Docs:
https://developers.cloudflare.com/workers/runtime-apis/request#incomingrequestcfproperties

Types:

workers-types/index.d.ts

Line 682 in c117b5a

interface IncomingRequestCfProperties {

For instance, notice that country property is described as string | null in docs and string in this lib. Or city defined as string | null in docs, but string | undefined in here. Similar mismatch applies to the rest properties.

Adding a types.d.ts file containing the following fixed type errors on VS Code for me, but I'm not sure why:

interface IncomingRequestCfProperties extends IncomingRequestCfProperties {}
