Please update Python and some package versions in line with Harmony library PR #106 / issue #99

## Description

Brandon Peña @brandonHaipas has kindly fixed some import errors that were breaking Colab in the Python core library.

You can see details in his [pull request](https://github.com/harmonydata/harmony/pull/106) and [the original issue](https://github.com/harmonydata/harmony/issues/99)

However the API has the same problems... Brandon wrote

```
I couldn't test the Harmony API because it has problems too; I'd have to fork it and correct the same issues. However, I managed to make it work for versions 3.9 to 3.13 with the same error I reported. I haven't had time to fix the API import errors yet, but some of them should be fixed by changing the package versions in the requirements.txt file to those used here.
```

Please can you check the `requirements` in Brandon's fork and bring Harmony API in line with that version? This might involve you updating the Dockerfile since Brandon changed `pyproject.toml` to update the Python version.

Start by reviewing Brandon's fork, PR #106, and issue #99, then compare the dependency versions in requirements.txt and pyproject.toml with the API repository. Check the Dockerfile for the Python version and dependency installation. Done means the API uses the aligned versions and no longer has the reported import errors.
