Fix author information alignment on posts

Short descriptions for authors are displayed in the same line as the Follow button on desktop. [Example](https://blog.glugmvit.com/expression-analysis/)

Either some custom css should be implemented in the [custom.scss](https://github.com/GlugMVIT/glugmvit.github.io/blob/master/assets/css/custom.scss) file to tackle this, or the [html](https://github.com/GlugMVIT/glugmvit.github.io/blob/master/_layouts/post.html) bootstrap container elements should be reorganised for the author information part.
