Hello, thanks for this Action. I'm experiencing some kind of unexpected behavior when using the --amend Git option, which I'm describing below.

Version of the Action
v4.3.0

Describe the bug
When using the --amend Git commit option on the commit_options field, the Action doesn't work if the working directory is clean, showing the message "Working tree clean. Nothing to commit.".

To Reproduce
Steps to reproduce the behavior:

• Use the --amend option on the commit_options field.
• When the working directory is empty, nothing is changed.

Expected behavior
The commit should be amended and pushed.

Used Workflow

   … # Some previews manual Git changes …

    - name: Commit changes
      uses: stefanzweifel/[email protected]
      with:
        commit_message: Bump version to ${{ steps.git-version.outputs.tag }}
        commit_options: --amend  # <-- This is 
        tagging_message: ${{ steps.git-version.outputs.tag }}

Additional context
My purpose is to perform some Git operations generating a new commit, and finally using this action and the --amend option to modify the commit and push it.
