MATLAB: set up CI for MacOS and Windows

[Remi-Gau]

Yes, I think setting up for at least MacOS will be relatively straight forward: You will just have to make another step like this one:

bids-matlab/.github/workflows/run_tests.yml

Lines 22 to 26 in 6c1dac6

	- name: Install dependencies
	run: |
	sudo apt-get -y -qq update
	sudo apt-get -y install octave liboctave-dev
	sudo apt-get -y install nodejs npm

but ensure that the (then two) steps run depending on the OS. that is, one runs only when OS=ubuntu, the other one only when OS=macOs

For the Ubuntu step, you leave everything as it is ... and for the MacOS step you adjust the "apt" installs with "brew" installs. The remaining action should work regardless of ubuntu or MacOS.

--> for windows it would go the same way ... first duplicating the steps, then making them run conditionally on a single OS only, and then adjusting the duplicated-OS-specific steps to actually work on that OS. I mean -> apt on ubuntu, brew on macOS, and maybe chocolatey on windows, ... and so on for all other commands.

I am not sure how easy this will be with windows. I once managed it for a similarly "complicated" install for the bids-validator. Hopefully it can serve as an example of what I mean:

See issue #165 as an example of something to check in CI!!

Won't do unless we start having significant number of bug reports specific to these platforms.
