[ci][python] Fix lint-python native-plan CI failure

[XiaoHongbo-Hope]

Purpose

The lint-python (3.11) CI leg builds pypaimon_rust and runs the mixed native-plan tests. table_update_test.py::test_literal_predicate_update_projects_only_row_id fails deterministically on that leg (values correct, row-group order flipped):

AssertionError: Lists differ: ['NYC', 'LA', 'Updated', 'Updated', 'Updated']
                          != ['Updated', 'Updated', 'Updated', 'NYC', 'LA']

Split order across row-id groups is not a cross-planner contract: engines may process splits in any order, and the Rust native plan can return the freshly updated group first. The test asserted an unsorted read, unlike its sibling tests which sort by id before asserting.

Bumping the pinned Rust revision alone does not fix this (verified on this PR's previous CI run with be5456e): apache/paimon-rust#717 aligns file order within row-id groups, not split order across groups.

Changes

• Sort the test's read output by id before asserting, matching the file's convention.
• Bump PYPAIMON_RUST_REV from c7a71f4 to current paimon-rust main be5456e, keeping the native leg on the contract-fixed planner (fix(scan): preserve Data Evolution file order in row-id groups paimon-rust#717, [flink] Use new ReadBuilder and WriteBuilder API in tests of paimon-flink module #719).

Tests

• The two failing variants (Batch/Stream) pass locally with a native-plan-enabled pypaimon_rust.
• flake8 passed.
