I have multiple folders in my project containing markdown files. I want to run `cspell` (and other tools) against them. Unfortunately, only the markdown files in the `docs` subfolder are returned in the blob.

Here's a snippet of an actions file:

```yaml
      - name: 'Spellchecking Content'
        run: |
          npm install cspell -g
          pwd
          ls ./**/*.md
          npx cspell $(ls ./**/*.md) -c ${{ github.workspace }}/cspell.json
        working-directory: ${{ github.workspace }}

```

Again, the problem is that the `ls ./**/*.md` in GitHub actions **only returns the markdown files in the `docs` folder** and no markdown files in the other subfolders.

**Troubleshooting:**

* `pwd` prints the correct, home folder of the project workspace
* `ls ./**/*.md` only lists the files in the `docs` subfolder
* I've attempted to set the `working-directory` explicitly
* The command works on my local machine, just not on GitHub
