duplicate key in image in file what-s-new-on-cpan---march-2018.md

hello

I identified a duplicate key "image" in metadata from file "what-s-new-on-cpan---march-2018.md".
I found that in working on issue #82

Here the content of metadata
{
"draft" : false,
"date" : "2018-04-02T21:48:15",
"thumbnail" : "/images/172/thumb_CD6B9F5C-F4AE-11E4-A230-A2654E9B8265.png",
"image" : "/images/172/CD6B9F5C-F4AE-11E4-A230-A2654E9B8265.png",
"tags" : ["duktape","firebase","freetype", "raspberry-pi", "anyevent","markua","mojolicious"],
"description" : "A curated look at March's new CPAN uploads",
"categories" : "cpan",
"title" : "What's new on CPAN - March 2018",
"image" : null,
"authors" : [
"david-farrell"
]
}

I will make a pull request with the patch soon.

Bests regards
