Adding a blog functionality to Community Contributions

[aktdenis]

Currently, the Community Contributions section on the Akash Network website serves as a placeholder linking to external content.

As we talked during wg-website meets we could introduce a blog functionality (mirroring the format and style used in the main blog) to showcase community-written blog posts directly on the Akash website.

Here is an example of a community member written blog post currently living in the main blog sections:

It looks like good.
