Add author name in intro and FULL STORY

[czgdp1807]

Describe the bug/feature

I observed that the name of the author is shown in the intro of the blog, but it is not shown in the FULL STORY i.e., the full post. It would be nice to show the author name both in the intro and the FULL STORY.

To Reproduce(for bug)

1. Go to https://codezonediitj.github.io/blog/, you will be able to see the name of the author.

2. Go to https://codezonediitj.github.io/blog/World-WiFi-Day/, and the author name is absent.
