title: github action cannot find the files of my R package
body: <p>I am trying to get Github Action to check my package. The packages compiles fine (not even a note) on my computer. I created a yaml script to go into the github workflow directory using <code>usethis::use_github_action_check_standard()</code> but it fails with a bunch of warnings like</p>
  <blockquote>
  <p>No files were found with the provided path: check. No artifacts will
  be uploaded.</p>
  </blockquote>
  <p>The path check is a temporary directory created by  <code>rcmdcheck</code> for storing files. So, I presume it is a problem connected with this command. But everything was created by the usethis utility and nobody else seems to have the same problem.</p>

  <p>I looked around a lot and the last fix I tried was to manually add a step to install imported and suggested packages, as suggested in <a href="https://stackoverflow.com/questions/61405539/use-github-package-r-actions">this post</a>, to no avail.</p>
  <p>What am I doing wrong? Thanks in advance.</p>
  <p>the yaml script is</p>
