Add CI workflow to check that sketches compile

[stefanotorneo]

This PR wants to avoid breaking examples, with a sketch, when dependencies change.

Why not use the GitHub Actions action we created specifically for this purpose?:

@per1234 has a valid point, but I would also consider compiling the sketch with profiles in order to be sure the list of libraries in the examples is correct, and there isn't any one missing.

That should work fine using the arduino/compile-sketches action. It uses the latest release version of Arduino CLI by default (configurable), so all the capabilities of Arduino CLI are available.

I didn't know about it.
I used it here.
Thanks.

Since in each sketch folder there is a sketch.yaml with platform and profile specified, is it necessary to specify them in the compile-sketches step config?

I would just specify the fqbn, i.e., arduino:zephyr:unoq, which was recently removed from the profile

Okay, I did it.
