title: How to upload artifacts to existing release?
body: <p>My workflow has automatic packaging and upload steps that package build artifacts and upload them to the workflow page. I also manually create releases.</p>
  <p>I would like to do the following:
  when I push to the tag that was created with a given release,
  I would like to upload the zipped artifact file to that release, so users can download
  the artifact. Any tips on how to do this ?</p>
  <p>Here is my <a href="https://github.com/GrokImageCompression/grok/blob/67504f98a6b3e3bc4f06c10dc30436c0abfd085b/.github/workflows/build.yml" rel="nofollow noreferrer">build yaml</a> file.</p>
  <p>Thanks!</p>
