Fix Windows tempdir cleanup race in test_vrt_tiled_scheduler_1714 (#1748)

Threaded dask writes can leave file handles briefly open after the
context manager exits, so Windows raises PermissionError [WinError 32]
on the recursive directory removal. Linux closes the handles before
shutil.rmtree walks the tree, so it never fails there.

Pass ignore_cleanup_errors=True on each TemporaryDirectory. The tests
verify the writes succeeded before the context exits, so the cleanup
failure is purely a Windows-side temp-file leak, not a real bug.
