Hard-coded authors printf of main.cpp

Hard-coded authors have been detected in `printf` functions of:
- [robotDevastation/main.cpp](https://github.com/asrob-uc3m/robotDevastation/blob/7930c61e8aa3d1f3c21cb2cb01753a2ae6e942dc/src/programs/robotDevastation/main.cpp#L48-L50)
- [rdServer/main.cpp](https://github.com/asrob-uc3m/robotDevastation/blob/7930c61e8aa3d1f3c21cb2cb01753a2ae6e942dc/src/programs/rdServer/main.cpp#L44-L46).

Similar steps to #110 and #118 should be taken.

Inspect the printf calls at lines 48–50 in src/programs/robotDevastation/main.cpp and lines 44–46 in src/programs/rdServer/main.cpp. Read issues #110 and #118 for the referenced approach; done means the authors are no longer hard-coded in these printf functions.
