Clean up pyproject.toml and package.json, fix poetry options (#25327)

- Reduce `pyproject.toml` and `package.json` to the minimal required
format, removing unneeded properties. `build-system` is not needed as
per
[this](https://github.com/python-poetry/poetry/issues/8110#issuecomment-1595846841).
- Fix `poetry.toml` options they were wrong previously.
- Add dependencies of poetry files to templates `files-changed`.
