fix(op_crates/fetch): check fetch() argument length

[ghost]

Related to #10203

Checks that fetch receives at least one arguement.

Relevant WebIDL:

partial interface mixin WindowOrWorkerGlobalScope {
  [NewObject] Promise<Response> fetch(RequestInfo input, optional RequestInit init = {});
};

- https://fetch.spec.whatwg.org/#fetch-method

input must be present.

Thanks! Must have missed this during fetch rewrite.

@lucacasonato Somewhat related, but I had barely left two comments on the rewrite PR, since I had barely checked it out within the hour. I'm not sure if those would be problematic or not, but it might be worth checking them out.
