Fetch all post comments when scanning for links

The new comment scan uses get_comments() without overriding the default number parameter. WordPress limits this call to the site’s comments_per_page option (10 by default), so only the first page of approved comments is inspected. Posts with more comments will have most comment links skipped, defeating the goal of detecting broken links across all comments. Specify 'number' => 0 or 'nopaging' => true in the arguments to ensure every approved comment is scanned.
