Issue:
Add proper indentation for HTML comments
- Maizzle Version: 4.6.0
- Node.js Version: 16.13.1

One of my most common use case with Maizzle is to build emails to then hand off to clients so they can either edit them manually or import on their own ESP or anything. As such, I like to be able to hand off a _clean_ HTML with proper indentation. While this mostly work great by default, it seems off with HTML comments (including `mso` conditionnal comments). The first line of an HTML is properly indented where it should be. But all the other lines miss one or more indentations.

```html
                        <div>
                          <a href="https://example.com" style="display: inline-block; border-radius: 4px; background-color: #4338ca; padding: 16px 24px; font-size: 16px; font-weight: 600; line-height: 1; color: #f8fafc; text-decoration: none">
                            <!--[if mso]>
      <i style="mso-font-width: -100%; letter-spacing: 32px; mso-text-raise: 30px" hidden>&nbsp;</i>
    <![endif]-->
                            <span style="mso-text-raise: 16px">
                          Read more &rarr;
                        </span>
                            <!--[if mso]>
      <i style="mso-font-width: -100%; letter-spacing: 32px;" hidden>&nbsp;</i>
    <![endif]-->
                          </a>
                        </div>
```

Not a big issue as this is purely code cosmetic, but I'd love if there were a quick fix here.

Pull request description:
feat: use prettier for prettify transformer
This PR changes the `prettify` transformer from `pretty` to `prettier` (which makes sense if you think about it 😂).

Main reason behind this is for HTML/MSO comments to be correctly indented too.

Closes #1071.
