add release body

[seiyria]

is it possible to add a release body? for example, with the actions/create-release@v1 action you can do this:

    - name: Create Release
      id: create_release
      uses: actions/create-release@v1
      env:
        GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} # This token is provided by Actions, you do not need to create your own token
      with:
        tag_name: ${{ github.ref }}
        release_name: Release ${{ github.ref }}
        body: |
          This is an automated release. See [the Changelog](link to my changelog) for more info.
        draft: false
        prerelease: false

electron-builder already supports a release-notes.md in the build resources folder, maybe there could be a setting to publish these release notes? That'd be awesome and save me a lot of manual work too.
