Remove questionable section on "unity builds" - this section cites some "build.sh" script with hardcoded paths to raylib, and on top of it it doesn't even describe a unity build
The unity script doesn't work if you dont have obj folder. I feel like there is no need to run the appliction inside the build script, that adds unneccessary lines/complexity also I changed the name from linux_platform to main cause that's more generic. I didn't know where to add "the simplest possible" thing, so I added it at the end. Tested on PopOS and Windows Subsystem Ubuntu.
