Linting not working following directions at https://github.com/github/super-linter/blob/master/README.md

Describe the bug

Did not get expected behavior following these directions (https://github.com/github/super-linter/blob/master/README.md):

To use this GitHub Action you will need to complete the following:

Create a new file in your repository called .github/workflows/linter.yml
Copy the example workflow from below into that new file, no extra configuration required
Commit that file to a new branch
Open up a pull request and observe the action working
Enjoy your more stable, and cleaner code base

To Reproduce
I followed the directions above at https://github.com/KarrLab/de_sim/tree/try_linter. See pull request KarrLab/de_sim#62.

Expected behavior
Instead of lint output, I find

grep: .github/workflows/linter.yml: No such file or directory

I'm probably doing something wrong.
Thanks for your attention.

Those grep are only informative and in the run i see the worflow run correctly and also in the logs i see:

So the linter is working as expected
