docs(readme): remove outdated storybook root-script gap notice

Removes the note stating that running Storybook from the repository
root isn't set up yet, along with the old cd-into-package workaround
instructions. This gap was closed by the root-level pnpm run
storybook script added in #11, so the outdated guidance is no longer
accurate.

 Component and browser tests run inside Docker (`docker-compose.test.yaml`), based on the same `Dockerfile.test` used to build the image CI tests against, to guarantee a reproducible browser environment — you don't need Playwright browsers installed locally. Locally this image is built on demand; in CI a prebuilt version of the same image is pulled directly (see [ADR-0002](./docs/src/content/docs/architecture/adr/000200-technology-stack.mdx) and the [Technology Architecture](./docs/src/content/docs/architecture/adm/technology-architecture.mdx#66-test-execution-environment) doc for details).
