Please provide install or install documentation that doesn't use snap on Linux

[dusanx]

For linux it is recommended to use snap: sudo snap install solar2d

Snap is very limited in reach as it heavily depends on systemd. There is many Linux distros that don't have systemd and therefore can't use snap. Many users don't want systemd on their machines, which blocks snap, which again blocks solar2d install. Please provide alternative way to install and use solar2d, that doesn't require snap. Documentation with manual install steps would be good enough. Thank you.
