Deno requests network access to "deno.land"

// add.ts
/**
 * @example add(1, 2)

export const add = (a: number, b: number) => a + b

// doc_test.ts
import { doctest } from "https://deno.land/x/doctest@0.3.0/mod.js"

Deno.test("doctest", doctest("./add.ts"))

$ deno test --allow-read
running 1 test from ./doc_test.ts
doctest ...┌ ⚠️  Deno requests network access to "deno.land".

└ Allow? [y/n/A] (y = yes, allow; n = no, deny; A = allow all net permissions) > 

I'm not sure what does this means.

Looks like it's how deno_doc works, it downloads https://deno.land/x/deno_doc@0.62.0/deno_doc_bg.wasm.

denoland/deno_doc#335 (comment) comments on this behaviour.

It still asks for permission every time the tests run, even when updating to 0.62.0.
