doc: Fix name of CRC algorithm in "Reliability" section.

This section claims we use CRC-32 for WAL records and two-phase state files, but we've actually used CRC-32C since v9.5 (commit 5028f22). Fix that. Reviewed-by: Robert Haas Discussion: https://postgr.es/m/ZrUFpLP-w2zTAHqq%40nathan Backpatch-through: 12
