Doc: fix outdated wording about parallel seq scans
56788d2 adjusted the parallel seq scan code so that instead of handing out a single block at a time to parallel workers, it now hands out ranges of blocks. Here we update the documentation which still claimed that workers received just 1 block at a time. Reported-by: Zhang Mingli Discussion: https://postgr.es/m/17c99615-2c3b-4e4e-9d0b-424a66a7bccd@Spark Backpatch-through: 14, where 56788d2 was added.
