Changes

• Rebased Kashish's help panel PR. The only change I've made was to how we're fetching the markdown files in order to fix the issue she was having with loading image.s

Testing

Steps:

1. Open the demo page and load a product.
2. There should be a new ? button in the top right. Clicking it should display some help content.

Will need some rebasing if Vite PR is merged but looks good

Not sure if this was due to rebased changes but getting this behavior on initial load on the help icon (transforms to icon after a few seconds).

I had just moved the source for the material symbols from the Vue component because I was dealing with that same issue. We really don't need to be adding a whole new font just for a question mark so I've removed it entirely and just replaced it with a regular ?.
