output doesn't work with single space strings

[dorner]

Describe the bug
When using the output parameter with an empty string, the files are concatenated together without any separator.

Workflow

    - name: Get file changes
      id: get_file_changes
      uses: trilom/file-changes-action@v1.2.0
      with:
        githubToken: ${{ secrets.GITHUB_TOKEN }}
        output: ' '
    - name: Echo file changes
      run: |
        echo Changed files: ${{ steps.get_file_changes.outputs.files }}

Expected behavior
Files should output with spaces between them, e.g. file1 file2. Instead, they are output together: file1file2

This should be all taken care of according to tests and stuff. Please let me know if you see differently

[dorner]

@trilom this may work in tests but I've confirmed it does not work in a real workflow. It looks like GitHub automatically trims all input strings when you call getInput(). Passing a single space string turns it into an empty string which the code then replaces with 'json'.

[dorner]

We'd likely need some kind of sentinel value for this case e.g. the word "space" to represent an empty space.

I arrived here from pre-commit/action#7 (comment)

However, I see that the space sentinel value was reverted in 86dd487

So, I assume ' ' Just Works™ now?
