fix(parquet): pass ReadHints into VECTOR ParquetFileBatchReader tests

[ChaomingZhangCN]

Purpose

Restore main CI after apache/paimon-cpp#198 merged on top of apache/paimon-cpp#209.

ParquetFileBatchReader::Create now requires a ReadHints argument. #198 added parquet_vector_io_test.cpp with the previous 6-argument call, so the merge compiled as:

parquet_vector_io_test.cpp:158: error: too few arguments to function call, expected 7, have 6
parquet_vector_io_test.cpp:179: error: too few arguments to function call, expected 7, have 6

That failed Build and Test on apache main after the merge (clang-debug-x86_64, gcc-debug-x86_64, gcc-debug-aarch64, sanitizers, and other jobs). Example: https://github.com/apache/paimon-cpp/actions/runs/32324365666

Pass /*hints=*/std::nullopt at both VECTOR test call sites, matching the other Parquet reader tests.

This branch is based on current main (afc8471). Open the same change against apache with:

apache/paimon-cpp@main...ChaomingZhangCN:paimon-cpp:cursor/fix-parquet-vector-create-hints-00b9

Tests

• ParquetVectorIoTest in src/paimon/format/parquet/parquet_vector_io_test.cpp
