- Rename image from `google-cloud-python-generator:latest` to
`python-librarian-generator:latest`
- Remove `service_config` since it's unused
- Rename `sourcePaths` to `source_roots`
- Preserve the following file patterns via `preserve_regex`
  - .OwlBot.yaml
  - CHANGELOG.md
  - docs/CHANGELOG.md
  - docs/README.rst
  - samples/README.txt
