Now modify the file `main.py` to receive a body from a `PUT` request.

Declare the body using standard Python types, thanks to Pydantic.

- [ ] Each commit in the pull request should have a meaningful subject line and body.
  Note that commits might be squashed by a maintainer on merge.
- [ ] Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.
