NextJSVite: Add @opentelemetry/api to optimizeDeps

[ndelangen]

What I did

I noticed this in CI:

 RUN  v4.0.17 /tmp/storybook-sandboxes/nextjs-vite-default-ts

8:55:57 AM [vite] (client) Forced re-optimization of dependencies
8:56:03 AM [vite] (client) ✨ new dependencies optimized: @opentelemetry/api
8:56:03 AM [vite] (client) ✨ optimized dependencies changed. reloading

[vitest] Vite unexpectedly reloaded a test. This may cause tests to fail, lead to flaky behaviour or duplicated test runs.
For a stable experience, please add mentioned dependencies to your config's `optimizeDeps.include` field manually.

See:
https://app.circleci.com/pipelines/github/storybookjs/storybook/113135/workflows/285df6d8-0fa1-4574-924a-582a9eaf097d/jobs/1019175

And I'm hoping adding an entry to optimizeDeps will resolve this.
