Description
Currently the lint:yaml and lint:twig command allow only one file or directory to be passed, e.g.: bin/console lint:yaml config/ etc.

I'd like to be able to pass multiple files/directories to these commands, which are then all linted. This is because as part of my CI, i lint all my yaml files, which can be in different directories.

For me the lint:twig isn't really needed, but if it is done for yaml, the twig one should work the same way, for consistency.
