…194237)

## Summary

Trying elastic#194082 again, this time wholly deleting
`kbn-ui-shared-deps-npm.v8.light/dark.css` as well 🤞

Original PR description:

> These files no longer contain any meaningful CSS used within Kibana as
of EUI's completed Emotion migration, and can be safely removed. EUI
will shortly no longer distribute these static `.css` files (although
`.scss` src files will still remain exported for the near future).
