Use profile picture as a rank icon

### Is your feature request related to a problem? Please describe.

I don't really want to show my rank on the stats page since its fairly low, but I think the GitHub icon could be improved by also allowing the use of the owners profile picture.

### Describe the solution you'd like

As the icon keyword you could use `profile` and then use the GitHub api to return the users profile picure.
The same user account can be used as the given rank username for the vercel API.
My idea would also keep the ring around the edge of the icon and just place the icon inside the ring like the current github logo does

### Describe alternatives you've considered

One alternative is allowing custom images but that would be more work than required for my request and would run into issues with pictures that dont conform to the circle used for the rank. So using the API is the simplier option especially since its already being used to retrieve stats for the rank.
