Closes #8032.
## Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
The main issue for #8032 is as what the errors said we have different schema
for result.schema which is `logical-expr schema` and
results.collect()[0].schema which is `physical-expr schema`.
I didn't find a way to ensure the `is_nullable` of the List are the same
between logical and physical expr, so I just add the comment aside it. But I
think we can ensure the `is_nullable` of the List element is the same since we
have `schema` info before we build physial-expr.
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Fix schema `is_nullable`
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
I did not test end to end like the issue reported, just make sure the schema
is the same.
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
