Review Comment:
The checked `withSQLConf` line, including its indentation and `10000` value,
is inserted verbatim by `parquet-fixture-row-groups.patch`; it is not inherited
from upstream Delta. No formatter runs between patch application and this
check. If upstream changes make the patch context incompatible, `git apply`
fails first. We're keeping the existing check because upstream formatting alone
cannot cause the stated failure after this patch applies successfully.
