Rename tag for latest with prefix/suffix

[rigon]

I have a project where I build two images:

• the first has the usual tags i.e. follow semver and latest is updated every time there is a new version;
• the second is tagged as the first, but with the suffix -slim

For that, I have the following configuration:

- name: Metadata
  uses: docker/metadata-action@v5
  with:
        flavor: |
          latest=auto
          suffix=-slim,onlatest=true
        tags: |
          type=ref,event=branch
          type=ref,event=pr
          type=semver,pattern={{version}}
          type=semver,pattern={{major}}.{{minor}}
          type=semver,pattern={{major}}

However, for the latest tag on the slim version, I’m getting latest-slim. Instead, I would like this tag to be simply slim for the latest version of the slim image.

How can I adjust my configuration to achieve this?
