Description

The "Gatsby Build" job was failing when content repo had markdown file that contains lines with only whitespace.
Trimming those lines has resolved issue.

To mitigate this issue in the future we have implemented workaround which trims empty lines before building static pages - SSWConsulting/SSW.Rules#1519
