Downloading a .docx file through docsify dev server corrupts file #1918

Bug Report

Downloading a linked a .docx Word file adds bites to file and corrupts it.

Sounds like it may be similar to this issue

Steps to reproduce

• create a link to a word file: [test file](templates/test.docx ':ignore')
• run docsify serve
• click the link, then click on the downloaded file

What is current behaviour

Opening downloaded file causes "Word found unreadable content.." message.

My test file is 12kb, but the copy in downloads folder is 20kb

What is the expected behaviour

Downloaded file would be same as source

Other relevant information

link looks fine when inspecting element:
<a href="templates/test.docx" target="_blank" rel="noopener">test file</a>

Download functions correctly when docs are viewed via github pages (and in the sandbox linked below) - only see the issue when using docsify dev server (so not impacting use - just confused me for a bit while writing the docs)

This stackoverflow question discusses similar behavior with an ASP.NET server.

• Bug does still occur when all/other plugins are disabled?

• Your OS: Win 11

• Node.js version: 16.13.2

• npm/yarn version: npm 8.1.2

• Browser version: Chrome 106/Firefox 106 (same issue in both)

• Docsify version: 4.4.4

• Docsify plugins: n/a

Please create a reproducible sandbox

Note: The download works in the sandbox test - assuming because the sandbox does not use the dev server

Mention the docsify version in which this bug was not present (if any)
