Export ParsedContent types

[cco3]

Is your feature request related to a problem? Please describe

Right now, the types in @nuxt/content/dist/runtime/types are not available in the package.json exports. This makes the eslint resolver choke when following the approach described in the docs.

import type { MarkdownParsedContent } from '@nuxt/content/dist/runtime/types'

[eslint]   1:1  error    Resolve error: Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './' is not defined by "exports" in /home/user/project/node_modules/@nuxt/content/package.json

Describe the solution you'd like

Add these types to the rest of the exported types (found at @nuxt/content/dist/types.d.ts)
