Action still runs a build step even when it's skipped

[cswilliams]

I have a common deployment workflow shared across both my staging and production environments with an if condition so it only triggers for production deployments:

  - name: Notify Rollbar of deployment
    continue-on-error: true
    uses: rollbar/github-deploy-action@eaf2a60ea238bd273226eee0ddceecfe5611964d # 2.1.2
    if: ${{ inputs.environment == 'production' }}

However, I noticed for my staging deployments, the action is still running a build / setup step at the start of my workflow that takes about 5 seconds:

Build container for action use: '/home/runner/work/_actions/rollbar/github-deploy-action/eaf2a60ea238bd273226eee0ddceecfe5611964d/Dockerfile'

I've been trying to get my deployments around a minute so this actually accounts for 5% of my total deployment time.

Is there a better way to skip this action for different environments or make the action smarter so it doesn't run this when it's being skipped?

Thanks
