Remove node polyfills no longer needed for rich text components (#2195)

# Pull Request

## 🤨 Rationale

Fixes #1700 These two polyfills were added in #1335 because markdown-it
implicitly depended on some functionality that existed in Node but not
browser environments. We've since upgraded markdown-it to a version that
expresses those dependencies on normal npm packages, so the polyfills
are no longer needed.
markdown-it/markdown-it#967

## 👩‍💻 Implementation

Remove rollup plugins and npm dependencies on those plugins that were
added in #1335.

## 🧪 Testing

Mostly depending on PR build but also spot checking rich text
functionality in storybook.
