Regenerating content is changing modified date of all blog posts

[ashb]

For example https://github.com/apache/airflow-site/commit/3c7cbb5d7a31ec1bd0e3bc044959ac84af15e41e

<meta property="article:modified_time" content="2020-12-01T12:39:55+01:00" /><meta property="og:site_name" content="Apache Airflow" />
<meta property="article:modified_time" content="2020-12-01T12:40:11+01:00" /><meta property="og:site_name" content="Apache Airflow" />

Just re-generating the site (but not changing the content) should not change these modification dates.

@alokshenoy Can you leave a comment here? I can only assign Apache members or people who participated in the ticket to the ticket.
