Issue:
`<script>` tags of type `application/json` are breaking production builds
## Summary

This was brought up in Slack, in that if you add a script tag of `type="application/json"`
```html
<html>
  <head>
    <script type="application/json">
      {"message": "calmer than you are"}
     </script>
  </head>
  <!-- ... --->
</html>
```


it will cause a build failure for Rollup / acorn, and was able to reproduce in one of the basic Greenwood test cases

## Details
Irony is, this is actually solved on the `v0.30.0-alpha.0` line but I snuck it into https://github.com/ProjectEvergreen/greenwood/commit/82460ea4f83a11810e24971d3008ab50f9dd3925#diff-1db487262eefc65529b67d5d3b1b1c040f9f0cb880d281965d61b11c5acaba4b (I got greedy and should have really made it its own bug) but since that release line is still a WIP with a couple heavy breaking changes, I think we should backport it.  (and I didn't write any test cases, shame on me 😭 )
