[Ruby] Add `ArrowFormat::RecordBatch#records`

[kou]

Describe the enhancement requested

It's a convenient API that extract rows from a record batch as Ruby object.

We already have ArrowFormat::RecordBatch#to_h but it returns values as columnar: {column1: [value1_1, value1_2, ...], column2: [value2_1, value2_2, ...], ...)

ArrowFormat::RecordBatch#records returns values as rows like Arrow::RecordBatch#records: [record1, record2, ...]`
