[SPARK-21267][DOCS][MINOR] Follow up to avoid referencing programming…

…-guide redirector ## What changes were proposed in this pull request? Update internal references from programming-guide to rdd-programming-guide See apache/spark-website@5ddf243 and apache#18485 (comment) Let's keep the redirector even if it's problematic to build, but not rely on it internally. ## How was this patch tested? (Doc build) Author: Sean Owen <[email protected]> Closes apache#18625 from srowen/SPARK-21267.2.
