chore(website): use workspace version of eui

[weronikaolejniczak]

Summary

When working with the new docs page, local changes to the EUI library are not reflected. That's because website package doesn't use workspace version of eui.

For context: Slack

QA

Test path

1. Run yarn to install deps.
2. Run yarn workspaces foreach -Rpti --from @elastic/eui-website run build to build all local dependency packages.
3. Run yarn workspace @elastic/eui-website start to run the new docs website.
4. Choose any component doc page. Change that component's source code (e.g. color).
5. Run yarn workspace @elastic/eui build and reload the page. The changes should be visible.

Changes look good to me 👍
I'd wait for @tkajtoch to determine if we can merge this or if there is something else needed first to ensure releases have correct versions?

Tested locally and it seems to work perfectly fine! LGTM
