chore: use different collection to rename

[paula-stacho]

Description

For some reason 2 of the collection rename tests keep failing in the CI. I can't reproduce it locally. From the screenshot it seems the screen is smaller and numbers collection is near the bottom of the viewport. So my hunch is that even though it's not captured on the screenshot, there was a toast over that item before.

Pull Request Overview

This PR addresses flaky E2E tests for collection renaming by changing the test collection from 'numbers' to 'csv-file'. The change aims to avoid potential toast notification overlays that may have been interfering with test interactions when 'numbers' appeared near the bottom of the viewport in CI environments.

If we're sure it's a toast, we can check for toasts before proceeding, this would be more stable than relying on a position of a different collection again, I'm afraid this can degrade again because we're not resolving the root cause here.

I'm fine if you want to merge this as a quick fix, but would be nice to follow-up
