Example Playgrounds don't work

[LeanderG]

Description

The examples playground-next, playground-next13-live-editing, playground-next13-rsc don't build. Running npm run build in the playgrounds throws various errors.

Suggested solution or improvement

One issue is described here but not fixed: https://github.com/storyblok/storyblok-react/issues/931 I tried to make a PR but couldn't due to unfixable linting errors. I suggest running npm run build for all playgrounds in Github Actions to verify that everything works.
