Fix MONTHS_OF_THE_YEAR constant name

[xhs345]

Had to fix the constant name, otherwise, it won't be displayed correctly in newer versions. See example https://learn.getgrav.org/16/cookbook/twig-recipes

In gateway/templates/partials/blog_item.html.twig look for the line:

{{ 'MONTHS_OF_THE_YEAR'|ta(page.date|date('n') - 1) }} {{ page.date|date('d, Y') }}

Change it to:

{{ page.date|date('M d, Y') }}

Issue fixed
