Does not support public repo action paths

[Nuru]

According to the official docs the syntax for referring to an action from a public repo is
{owner}/{repo}@{ref} or {owner}/{repo}/{path}@{ref}.

act does not support the {owner}/{repo}/{path}@{ref} syntax.

Given workflow path-example.yml

name: Path Example
on: pull_request

jobs:
  example:
    runs-on: ubuntu-latest
    steps:
    - uses: cloudposse/actions/github/slash-command-dispatch@0.14.0

act treats the path as part of the repo name, not a path within it

 $ act
[Path Example/example] 🚀  Start image=node:12.6-buster-slim
[Path Example/example]   🐳  docker run image=node:12.6-buster-slim entrypoint=["/usr/bin/tail" "-f" "/dev/null"] cmd=[]
[Path Example/example]   🐳  docker cp src=/Users/nuru/dev/example/. dst=/github/workspace
[Path Example/example] ⭐  Run cloudposse/actions/github/slash-command-dispatch@0.14.0
[Path Example/example]   ☁  git clone 'https://github.com/cloudposse/actions' # ref=0.14.0
[Path Example/example]   ❌  Failure - cloudposse/actions/github/slash-command-dispatch@0.14.0
Error: open /Users/nuru/.cache/act/cloudposse-actions-github-slash-command-dispatch@0.14.0/action.yaml: no such file or directory
