CI: YAML check

[fishnux]

For every Git commit, YAML files must be checked to ensure proper validation.

Continuous integration software suggestions are welcome. I only used GitLab's CI.

YAML files are now being validated in the deployer entrypoint script

swarmlet/modules/core/deployer/entrypoint

Lines 25 to 26 in 89c805d

	python3 -c 'import yaml, sys; yaml.safe_load(sys.stdin)' <"$COMPOSE_FILE" &>/dev/null
	[[ $? == "1" ]] && exit 1

I'm re-opening this issue because I'm referring to Continuous Integration checks, which aren't implemented yet. The deployer checks are still very useful! 😃

I can help you with that. I think GithubActions can do the job.

Just provide a Makefile with a task/target make lint-yaml.
