bug: fix the planBase(schema...) of the StreamSink

[st1page]

It should filter the invisible columns because

risingwave/src/stream/src/executor/sink.rs

Lines 414 to 424 in c08aa2b

	let mut log_reader = log_reader
	.transform_chunk(move |chunk| {
	if visible_columns.len() != columns.len() {
	// Do projection here because we may have columns that aren't visible to
	// the downstream.
	chunk.project(&visible_columns)
	} else {
	chunk
	}
	})
	.monitored(metrics);

But It does not introduce issues so far because no place use the sink node's property.

For sink into table, the sink's schema does not filter all the invisible columns...
