Update GitHub Actions workflow for Docker image builds

- Change workflow name to 'build-images-main' for better clarity
- Limit workflow to trigger only on pushes to the 'main' branch
- Add steps to build and push a new GPU-enabled Docker image (scriberr:main-gpu) alongside the existing main image
- Create workflow "build-images-nightly.yml" to allow for images that are still in testing to be built when pushed to the Nightly branch. It is limited to the Nightly branch.
- Nightly branch will build a GPU and CPU only version.
- Ensure each image is verified for multi-platform support after the build process
