  1. fix CRC algorithm in WAL reliability docs

    I noticed that the "WAL reliability" documentation says that we use CRC-32
    for WAL records and two-phase state files, but we've actually used CRC-32C
    since v9.5 (commit 5028f22).  I've attached a short patch to fix this that
    I think should be back-patched to all supported versions.
    
    I've attached a second patch that standardizes how we refer to these kinds
    of algorithms in our docs.  Specifically, it adds dashes (e.g., "CRC-32C"
    instead of "CRC32C").  Wikipedia uses this style pretty consistently [0]
    [1] [2], and so I think we should, too.  I don't think this one needs to be
    back-patched.
    
    Thoughts?
