Attempt to replace pkg_resources uses, generally bump to Python 3.10+ maintenance etc.

Hi Tim

I have had a go at this.

I used your ChatGPT suggestions.

I have tested on the most recent versions of Python 3.10, 3.11, 3.12, and 3.13 and they all pass nbdev_test (as you can see from the GitHub Actions workflow I've amended) and a quarto render of a test Quarto document.

However, I have a mysterious problem. When I run this under the recently released Python 3.14.0 I obtain some sort of problem originating from within Stata's pystata. Weirdly nbdev_test passes. But when I run a test quarto render the kernel hangs at the first Stata chunk. To see more I converted my test qmd file to a Jupyter notebook.

First create a UV virtual environment with Python 3.14.0 and activate it

uv venv --python 3.14.0
source .venv/bin/activate

Then add the packages in the pyproject.toml and nbstata

uv sync

Install the kernel

python -m nbstata.install

Then this will hang, where my test.qmd is simply

---
jupyter: nbstata
format:
  html:
    embed-resources: true
---

```{stata}
about
```

```{stata}
twoway function x^2
```

quarto render test.qmd

Kill that with Ctrl+C and convert qmd file to ipynb

quarto convert test.qmd

Then open the ipynb in JupyerLab

jupyter lab test.ipynb

Then executing a stata chunk, the error I obtain is:

Would you have any ideas? I might ask StataCorp. Tech Support about it.

Anyway even if you don't take this, maybe a useful starting place for your own commits.

Closes #58

Closes #65 (because it includes those commits)

Thank you! I've been delayed on reviewing but maybe by the end of this week.

I've been trying to think about the reason for the problem on Python 3.14. My best guess is that it's some problem to do with the filenames being the same, i.e. stata.py in nbstata trying to import something from stata.py in pystata. But so far I don't know how to fix.

Also I wasn't sure if I needed to add corresponding notebooks for the new _resources.py and _version_helper.py files.
