Fix: Support multiple compose files in swarm mode

[theolujay]

• Added file splitting logic for swarm mode (similar to compose mode)
• Each file now gets its own -c flag in swarm deployments
• Fixes issue where multiple files were treated as a single filename

Before: docker stack deploy -c "file1 file2" stack-name
After: docker stack deploy -c file1 -c file2 stack-name

Since I use a real test and not a mock one it cant run on public PRs, but I checked out the PR locally and ran the test and it seems to work great. ✅

I also hate that GitHub has safe workflows disabled for new contributors by default. I enabled the Lint workflow. Looks like all you need to do is run Prettier on the README.md and it should be good to go.

Great Work. Thanks for the contribution! 🚢

I wasn't sure what wasn't passing... just figured you might check it out yourself. I see it was the README I needed to reformat. I've now done that and it passes. I didn't know about the safe workflows thing though.

Great Work. Thanks for the contribution! 🚢

Thank you too.
