chore: Format examples in doc strings - catalog listing (#18335)

## Which issue does this PR close?
Part of #16915

## Rationale for this change
Format code examples in documentation comments to improve readability
and maintain consistent code style across the codebase. This is part of
a multi-PR effort to format all doc comment examples and eventually
enable CI checks to enforce this formatting.

## What changes are included in this PR?
Run `cargo fmt -p datafusion-catalog-listing -- --config
format_code_in_doc_comments=true`

## Are these changes tested?
No testing needed - this is purely a formatting change with no
functional modifications.

## Are there any user-facing changes?
No - this only affects documentation formatting.
