[FR]: ls-lint

### What is the current behavior?

_No response_

### Describe the feature

Would be great to use [ls-lint](https://github.com/loeffel-io/ls-lint) from rules_lint for files/directories

Start by reviewing the rules_lint repository and the linked ls-lint project to understand how external file and directory linting should be integrated. Done means ls-lint can be used through rules_lint with documented configuration and coverage for the supported files and directories.
