Update README.md

[Jpxe]

I just installed the debug build on Fedora. I had to do a bit of trail and error to find out I also needed to install Cargo and the Godot export template, as well as extract it in the right directory. These instructions might make it a bit easier.

Looks pretty good the lines added after the first one for fedora should be common across all distro, mainly about getting the export template and putting it in the right place. If you can update that the rest looks good.

Thanks for the contribution!

How about this? I did som searching for what terminal commands should work for different distros and did some slight text changes as well
