Subject: [PATCH] Type the `verifyClient` callback in the `ws` library
 definition

Summary:
The `ws` v7 library definition declared `verifyClient` as `() => unknown`, so callers that read the connection info (such as `origin`) failed to type-check. Type its first argument as the info object `ws` passes (`origin`, `secure` and `req`), matching the React Native copy of this definition.

Changelog: [Internal]
