`Fetch: Cross-Origin Requests` article wording

Article: Fetch: Cross-Origin Requests

I may be nitpicking, but I had to google what was wrong with my preflight request when it had ~10 headers and received a 204 response.

5-network/05-fetch-crossorigin/article.md を開き、206 行目と 212 行目付近の文言を確認します。これらの記述を、リンク先の MDN 記事および Fetch specification と比較します。記事が、ヘッダーが正確に 3 つである、または 200 応答 בלבדであると示唆しなくなり、成功した preflight 応答について正確なガイダンスを維持していれば完了です。
