check: support directory scan

[Dentrax]

TL;DR

It would be nice to support directory inputs for check subcommand:

$ ratchet check .github/workflows/
failed to parse .github/workflows/: failed to decode yaml: yaml: input error: read .github/workflows/: is a directory

Detailed design

If given arg is directory, traverse all `.yml | .yaml` files (it's ok to ignore symlinks for now).

If given arg is file, it should work as is.

Example output format:

[PASS] .github/workflows/foo.yaml
[FAIL] .github/workflows/bar.yaml
[PASS] .github/workflows/baz.yaml

Hi @Dentrax

This gets really complex with authentication, so I would prefer not to support a collection of files. Instead, you can use unix commands like find an xargs to accomplish this:

find . -name '*.yml' -exec ratchet check {} \;

Yes, I've tried the same method to scan directory but if we want to implement this in the CI, things get complicated since our entry point is ratchet in Docker image. So I want to use the following use-case scenario. Notice that we can not use the way you provided above.

# Example of checking all versions under .github/workflows/ are pinned.
      - uses: 'docker://ghcr.io/sethvargo/ratchet:0.2.3'
        with:
          args: 'check .github/workflows/'

We created a simple PR anyway 🤷‍♂️ #29 (@developer-guy)
