Add CI workflow to validate cookiecutter templates


*F´ Version*
*Affected Component*

Feature Description

Add CI workflow to validate the cookiecutter templates. Something in the likes of

fprime-bootstrap project
cd project
fprime-util new --deployment
cd deployment
fprime-util generate
fprime-util build

And probably something for component as well. We probably want to

cd project/fprime
git checkout devel

too.

Make sure cookiecutter templates don't go out of date without needing to test locally for each release.
