Subject: [PATCH] GH-1454: Declare ID as nullable in the local files Substrait
 test plan

local_files_users.json declared ID as required, but the Parquet file
the test reads has an optional id column and the test expects a
nullable ID. Arrow C++ main now keeps the input nullability of
projected fields (apache/arrow#51691), so the scan returned ID as not
null and testRunQueryLocalFiles failed in the nightly build.
