fix bad changeset and avoid warnings

[thomasheyenbrock]

I added a bad changeset in #2397 that contained ignored packages. This currently breaks the release workflow: https://github.com/graphql/graphiql/runs/6395880044?check_suite_focus=true

I also changed the dependencies in the webpack example to avoid the warnings printed above the error.
