Remove @storybook/html peer dependency from root package.json and re-enable audit for prod

[jattasNI]

Pull Request

🤨 Rationale

Fixes #1317.

The npm audit of production dependencies was failing because of deps that Storybook brought in. But Storybook should really be a dev dependency.

Storybook is listed as a production dependency because it's in peerDependencies in the root package.json. We added it there in this commit of the PR that migrated us to Storybook 7. I believe the rationale was that it was necessary to apply a patch to the package. (I'd like to remove that patch but I think it's not possible until storybookjs/storybook#22384 is available. Currently it's only released in an alpha branch)

👩‍💻 Implementation

1. Remove @storybook/html from peerDependencies in the root package.json
2. git clean -fdx
3. npm install to regenerate package-lock.json
4. Re-enable audit for all severity levels for prod dependencies

🧪 Testing

I locally verified that the patch was still applied to the file inside node_modules. If it isn't applied, I believe we'd see a build error.

I locally verified that npm audit --only=prod succeeds now.

Otherwise relying on the PR build.
