Bug in Chapter c05_08

[R3c0ger]

I have found an issue in Section 5.8 of the eBook regarding the regular expression used for adding quotes to headers copied from the browser. The current regular expression and replacement command will include any spaces after the colon inside the quotes, which is incorrect.
5.8节中使用的正则表达式和替换命令会将冒号后的空格包含在引号内，这恐怕不是咱想达到的效果（笑）。

修改建议：

第一行【查找】：  (.*?):\s*(.*)
第二行【替换】：  '$1': '$2',
