How do I find the tag associated with a commit as part of a github pull-request action?

I've got this step:

- name: getSumac
  uses: actions/checkout@v2
  with:
    repository: yma/sumac
    ref: ${{ github.ref }}

That works when the action is triggered by pushing a tag. But when a PR is created or updated, github.ref is something like refs/pull/99/merge and the getSumac step fails.

On the command-line, I would run something like $( git describe --tags | grep -Eo '^v[.0-9]+' ) to get the most recent tag. Is there a way to do that in a github action step?

Turns out in this case I could set a VERSION env var, so I could do something like this:

steps:
- name: Override the VERSION env var
  run: |
    VERSION=${VERSION:-$(git describe --tags | sed 's/^v//')}
    if [ -n "$VERSION" ] ; then
      echo "VERSION=$VERSION" >> $GITHUB_ENV
    fi

And the actions I'm using just use $GITHUB_ENV (I never reference it explicitly in the other steps).
