`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.

打开 5-network/05-fetch-crossorigin/article.md，检查第 206 行和第 212 行附近的措辞。将这些表述与链接的 MDN 文章和 Fetch specification 进行比较。完成的标准是：文章不再暗示恰好有三个标头或只有 200 响应，同时保留关于成功 preflight 响应的准确指导。
