Github: add workflow support

[RichardFevrier]

Providing automatic release + binaries generation as #1 suggested (on push new tag). Generates binaries for amd + arm for darwin + linux + windows. Tested on my repo 🙂

Edit: I did not include the install.sh script in the final archive. Maybe something to add 🤔 or we should really merge it inside the go binary.

What about FreeBSD? 😉️

Perhaps we can also consider keeping a very simple install.sh so that people can download and install app with a single command like Homebrew and distrobox, etc? The install script would mostly be there to ensure that where ever app is placed, it's part of $PATH?

Freebsd added 🙂

Sure to keep it very simple, it probably needs a lïttle rewrite cause:

• no need to compile app binaries anymore with this pull request
• installing brew, go, whatever could be wished by user later on, so having it in the binary instead could solve that (btw what about people on linux wanting install brew, what about people already having brew on their system; I think its not checked (also applies for other like flatpak, ...))
• should handle more shells (my fish as no idea about .profile)

All of this should probably be in a separated issue to improve install.sh script.
