Added scaleway logo + entry

While investigating the RISC-V ecosystem, we noticed that there isn't an easy way for developers to build and test their software on native hardware without buying it.

So we integrated custom RISC-V servers in our bare metal servers infrastructure and made them available to the public to enable the building, porting and testing of more native RISC-V software.
