Multiline output

[rosshamish]

Hey there, thanks for the action. Would you be open to accepting a PR that adds support for multiline output? It's helpful for example when outputting one field from each item in a list. Right now, if the jq output has multiple lines, only the first line is set as the output, and the rest of the lines are just written to stdout.

It would look like this:

    - name: Extract contributed themes from package.json
      uses: .sergeysova/jq-action@v2
      id: themes
      with:
        cmd: 'jq .contributes.themes[].path ${{ inputs.working-directory }}/package.json --raw-output'
        multiline: true

And then the multiline output can be used like

    - name: Verify each contributed theme exists
      shell: bash
      run: |
        themes_in_package_json="${{ steps.themes.outputs.value }}"
        for theme in $themes_in_package_json; do
            ....
        done

Let me know! Thanks.
