Support custom destination folder

[dantehemerson]

I want to set as destination folder the current working folder.

screenshot-website/index.js

Line 17 in 8df7c0f

const destFolder = process.env.RUNNER_TEMP;

Just adding that I would also use a feature to set a custom destination folder.

Right now I have a step in my workflow right after screenshote-website runs, that will copy the generated screenshot to where I want it to be like this:

    - name: Screenshot Markmap Website
      id: screenshot-generator
      uses: swinton/screenshot-website@main
      with:
        <<removed as not helpful for example>>
    - name: Copy Screenshot
      run: cp ${{ steps.screenshot-generator.outputs.path }} .
