CI: correct error msg in `test_view_index`
CI failed, the reason: `AssertionError: Regex pattern did not match.`

Replaced error msg `'Cannot change data-type for object array'` with `'Cannot change data-type for array of references.'`
Thanks for the quick fix! Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
git checkout 2.2.x
git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
git cherry-pick -x -m1 f56cba900e9f035b54519a0aa7d027bef01fc50b
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
git commit -am 'Backport PR #58181: CI: correct error msg in `test_view_index`'
```

4. Push to a named branch:

```
git push YOURFORK 2.2.x:auto-backport-of-pr-58181-on-2.2.x
```

5. Create a PR against branch 2.2.x, I would have named this PR:

> "Backport PR #58181 on branch 2.2.x (CI: correct error msg in `test_view_index`)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the `Still Needs Manual Backport` label once the PR gets merged.
