Generator: marked npm package @latest breaks demo page

[Eliza-Huang]

Describe the bug

When developing, the demo page that pops up is blank and there is an error in the console inside of devtools saying that marked from the marked npm package is not a function. There was a new version of marked released at around 1pm on 10/6/2021 and it's been broken since.

This only happens with components that are built using the WC Generator after this commit: 559b393#diff-38c424b322c7a39d8611e7d4df120ae548e41ed8efeee73bfe92c351fc880bfd.

To Reproduce

Steps to reproduce the behavior:

1. Run npm run dev and npm run serve on any auro component.
2. Wait for the demo page to pop up
3. Notice that the page is blank and there's an error in the console

Expected behavior

The demo page pops up like it is supposed to.

Screenshots

Desktop (please complete the following information):

• OS: Windows
• Browser Chrome (tested only in Chrome but should happen on all browsers)
• Version 94

Additional context

Locking the marked version @3.0.4 in the file https://github.com/AlaskaAirlines/WC-Generator/blob/2d0867c7d6864908c86cc7948f4851f15615920d/template/demo/index.html should fix it.
