Output details about the failures when running in passive mode

[Harry Cruse]

Is your feature request related to a problem? Please describe.
When running via the CLI in passive mode with the --passive flag, the output only says which files have failed, but doesn't give any detail about what the failures are

Describe the solution you'd like
When a file fails the checks, the output should describe the failures

Additional context
I had an issue today where all files are failing the check when run on the build pipeline but passing locally, so it was really hard to debug. It turned out to be related to line endings (XamlStyler enforces CRLF, which can't be changed until #295 is merged), but it would've been nice if the output could've told me what the problem was
