    Remove erroneous newline in sample generation

    The sample generation code for policies has a couple different cases
    that make sure deprecated rules have descriptions and reasoning
    formatted in the comment section. One of the cases that handles
    policies deprecated for removal was injecting an extra newline in the
    comment text that threw off the formatting of the sample, leaving
    the subsequent policy uncommented, and visually unpleasing.

    This commit removes the extra newline in the formatting logic for
    deprecated policies and adds a test case for the behavior.
