✨ feat(server): Rename /netris/proton to netris-proton (#61)

## Description

**What issue are you solving (or what feature are you adding) and how
are you doing it?**

With help from @djpremier, rename `/usr/bin/netris/proton` as "the
script cannot be found in bash `(eg.: $ proton -r /games/AlanWake.exe)`
if it is in the subdirectory of /usr/bin, probably because it is found
in a subdir inside `/usr/bin` "
