explain-about-others-linux distrib-instalattion

2 month ago I wanted to install the donkey car on my machine, but I use Manjaro (arch) distribution Linux and when I saw the only Ubuntu(Debian) option, I decided don't try install it by doc download link, i search by the source code and try build it on my arch Linux, but it spent so much time, so I tried download it to verify what's the simulator extension, and it was a binary! Because the docs said that release is built to Ubuntu(Debian) I thought it was a .deb file, but it isn't, its was a binary file! if I knew it was a binary file I already tried run it on my machine before, and it doesn't was writed on docs.

Fixed conda install path

Update install_software.md

Update install_software.md

The conda install path was pointing to `envs/mac.yml`, but nowhere before that instruction does it tell the reader to `cd` into the `install` subdirectory first, so for the command to work, `install` must be prepended to the path.
