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.
