bypass if user used a real microsoft minecraft account on ATLauncher AT Launcher and allows him to use offline mode

⚠️ NO LONGER WORKS ⚠️

ATLauncher made a commit that checks the validity of a minecraft account. Last known version that the bypass works on is 3.4.28.1 that can be found here

Linux Shell (flatpak) install
