adding empty line after badge so table renders properly

[joshjohanning]

Appending an empty line after the badge to render the markdown table properly.

Before:

Package	Line Rate	Branch Rate	Complexity
PrimeService	100%	100%	6
Summary	100% (12 / 12)	100% (6 / 6)	6

After:

Package	Line Rate	Branch Rate	Complexity
PrimeService	100%	100%	6
Summary	100% (12 / 12)	100% (6 / 6)	6

@joshjohanning I haven't had any issues with the markdown output but since you have I've merged the change, thanks.

@irongut maybe it was because I was using both banner and table output in the PR? Either way if there's not an extra line break between, at least for me, GitHub doesn't seem to want to render the table properly. Maybe a newer thing - but thanks for the merge!
