Adds workflow to build and deploy internal blog website powered by Hugo and GitHub pages.

[iramykytyn]

What does it do?

• Adds blog folder, which contains static pages for internal blog website powered with GitHub Pages and Hugo.
• Adds auto-deployment of the blog on PR or push to dev or main branches.
• Adds PR review template. It will be automatically added to PR description after it's merged to main, until then please insert it manually.
• See my first blog post about the purpose of the blog and how to add new posts.

What else do you need to know?

Currently, there are two theme options, ananke and papermod. The website is configured to use PaperMod right now.
We can decide later which one to use. For now I like papermod better since it looks like more nerdy :)
