Download shfmt from GitHub releases

[latipun7]

Currently shfmt is installed using go. I'm not go developer so installing go which is so huge imo only for installing shfmt is kinda overkill.

shfmt GitHub release already has the latest version of pre-build of that tools, but it's not zip or tarball. They are the executable itself. So, after downloading that, it just needs to be renamed into shfmt or shfmt.exe and set the executable.

Does this approach could be supported? Thank you very much for this great tool.

Hello! Yes, definitely. Prebuilt packages are generally preferred when available. PR to change this is very much welcomed, #434 may be used as a reference (it transformed an installer from using go to GitHub release assets). Otherwise I'll get around to it eventually!

Thanks. I'll create new issue from this discussion for tracking.
