Commit version in the deployment

Question

Hello, I have a question about deployment, I've tried to have a look to the docs but I couldn't find anything, I'm deploying my service using a github action:

```
deploy-railway:
    name: Deploy app
    runs-on: ubuntu-latest
    needs: [test]
    if: github.ref == 'refs/heads/main'
    container: ghcr.io/railwayapp/cli:latest
    env:
      SVC_ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
      RAILWAY_TOKEN: ${{ secrets.RAILWAY_TOKEN }}
    steps:
      - uses: actions/checkout@v3
      - run: railway up --service=${{ env.SVC_ID }}
```

I was wondering, is there a way to attach the git commit to the deployment details? something like:

```railway up --service=${{ env.SVC_ID }} --commit=${{ GIT_COMMIT }}```
