Stylesheets placed in `styles` directory aren't referenced/used on website

Summary

I made a stylesheet: styles/website.css. This stylesheet should be referenced on the website.

• HonKit version: 3.5.1

Steps to reproduce

1. Install HonKit and run yarn run honkit init
2. Do something that would normally be styled by CSS (e.g., add an img tag with a certain class attribute).
3. Create a styles/website.css file and add to it.
4. Create a book.json file with contents below.
5. Run yarn run honkit serve and navigate to the appropriate webpage.

• Link to code example:

book.json contents

{}

package.json contents

{
  "name": "honkit-demo",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "dependencies": {
    "honkit": "^3.5.1"
  },
  "scripts": {
    "build": "honkit build",
    "serve": "honkit serve"
  }
}

Directory structure

.
├── README.md
├── SUMMARY.md
├── _book
├── book.json
├── node_modules
├── package.json
├── styles
└── yarn.lock

3 directories, 5 files

Expected results

The stylesheet should be included in the HTML source code, with its style changes being implemented onto the site.

Actual results

The stylesheet is not included in the HTML source code.
