fixes expansion panel

[jpvajda]

Steps to reproduce

1. go to this page: https://www.apollographql.com/docs/react/data/error-handling/
2. try to expand the expansion panels

This PR fixes a problem where the expansion panels in this docs page wouldn't expand. There seemed to be an old import reference to a deprecated component which might have been impacting the other components on this page. The link chain code seemed to be referencing what is documented here. . So I just added that code in manually.

Also it seems we no longer need an important statement for components, based on this section of docs readme.

The Linkedchain component no longer seems to be available in the docs source code.

@StephenBarlow I was hoping you could review this fix for me.

Looks good, thanks for catching! One request around list bullets

@benjamn I'm having an issue with a test failing on Circle CI but all tests pass locally. I've even ran the individual failed test independently and that also passes.

jest --config ./config/jest.config.js --testRegex __tests__/batchLink.ts

all tests pass

batchLink.ts test passes

Any thoughts on what might be the issue here?

@jpvajda I just rebased against main and the tests passed ... 🤷‍♂️. Gremlins in the system for sure, but we should now be good to go. Thanks!
