Add bash-3.2

Would be nice to test for script compatibility with MacOS. See the AUR package here. Comes with its own set of patches. Not sure how hard it would be to port them, or if the MSYS2 patches with them.

Not really something we care about.

Can't you use zsh on MacOS nowadays? Or bash from homebrew?

[500-internal-server-error]

That is one solution, but then my scripts are uncheckable by shellcheck (though in practice, pretending it's bash is good enough). Also zsh is rarer on Linux. My goal is to have a "universal" script, which works out-of-the-box on Windows (Cygwin/MSYS2/WSL), MacOS, and Linux. Among these targets, the lowest common denominator is bash, specifically bash-3.2. I guess I can target sh, but it's a significantly reduced shell compared to bash.

Yeah, tricky
