Update github logo for PharmaR

[elong0527]

Could you update our github logo?

https://github.com/pharmaR to be consistent with the website? https://www.pharmar.org/

Hi @dgkf - just looking into some of our older issues on this repository.

Is this something that you can update our main GitHub logo with? I do not have permissions for any changes to https://github.com/pharmaR . I think this file could work well since it is roughly square. Let me know if a better image should be rendered for you to make the update.
