get back changelog-sections 🙏

**Is your feature request related to a problem? Please describe.**
I'm using release-please within an organization context. it is very powerful and it is a must-have when comes time to deploy applications.
The objective would be to roll out this action wrapped within a reusable github workflow so that it comes with a pre-existing set of configuration.
ex
```yaml
name: 'release-please'
on:
workflow_call:
# eventually add debug input
jobs:
release-please:
runs-on: ubuntu-latest
steps:
- uses: googleapis/release-please-action@v4
id: release
with:
token: ${{ secrets.TOKEN }}
config-file: .release-please-config.json
manifest-file: .release-please-manifest.json
- name: debug
run: |
echo "Release PR: ${{ steps.release.outputs.releases_created }}"
```

**Describe the solution you'd like**
I wish I could specify the `changelog-sections` from this workflow so that I don't need to repeat it in every repository that use it the repo above
```yaml
name: 'release-please'
on:
workflow_call:
# eventually add debug input
jobs:
release-please:
runs-on: ubuntu-latest
steps:
- uses: googleapis/release-please-action@v4
id: release
with:
token: ${{ secrets.ARGOCD_AUTO_DEPLOY_GH_TOKEN }}
config-file: .release-please-config.json
manifest-file: .release-please-manifest.json

```

**Describe alternatives you've considered**
replicate within each repo but this is not convenient

Start by tracing how the action exposes and forwards workflow inputs, then compare that path with the existing changelog-sections configuration shown in the issue. Add support for supplying those sections through the reusable workflow and verify that the example workflow passes them through as intended.
