[Ruby] Add tests to consider an empty chunked array for Arrow::Table#each_raw_records

[otegami]

Describe the enhancement requested

Some test cases currently couldn't consider an empty chunked array.
So we should add this test pattern to the other test cases about Arrow::Table#each_raw_records like the following.

arrow/ruby/red-arrow/test/each-raw-record/test-basic-arrays.rb

Lines 522 to 529 in a526ba6

	record_batch = Arrow::RecordBatch.new(schema, records)
	# Multiple chunks
	record_batches = [
	record_batch.slice(0, 2),
	record_batch.slice(2, 0), # Empty chunk
	record_batch.slice(2, record_batch.length - 2),
	]
	Arrow::Table.new(schema, record_batches)

You need to use just "take": https://arrow.apache.org/docs/dev/developers/bug_reports.html#issue-assignment
