Add CI workflow and rename playground packages

- Introduced a new CI workflow in `.github/workflows/ci.yaml` to automate builds and checks on push and pull request events.
- Renamed playground package names for consistency, changing prefixes from `@storyblok/richtext-playground-*` to `@storyblok/playground-richtext-*` across multiple package.json files in the richtext playground.
