Add user README to users profile

What does this MR do and why?

Adds the ability for users to create a project that matches their own username and as long as this project is public we will then display the content of a README if it exists in the project on the users overview tab.

How to set up and validate locally

• Create a new project that matches your current users username. ie. for me that would be iamphill.
  • Make sure that this project is public
• Create a README inside of this project
• View your users profile
