⭐️ support formatting multiple policy bundle files

[chris-rock]

fixes #109

cnspec bundle fmt example-policy.mql.yaml policy/examples/example.mql.yaml
→ format policy bundle(s) file=example-policy.mql.yaml
→ format file filename=example-policy.mql.yaml
→ format policy bundle(s) file=policy/examples/example.mql.yaml
→ format file filename=policy/examples/example.mql.yaml
→ completed formatting policy bundle(s)

I'd also like to mention that you can also pass-in a directory. cnspec bundle fmt will recursively walk the directory and format all .mql.yaml files.
