Use pyo3 experimental-inspect instead of generate_stubs.py

[haixuanTao]

Currently dora use a custom script called generate_stubs.py to generate type hinting in python.

Unfortunately, this typing is not perfect as it requires manual type hinting and has many depreciated feature when linted with:

uvx ruff check --select UP

We can try to run pyo3 with the feature flag experimental-inspect and see if this can be a good automatic stub generator.

To do this, we just need to replace in Cargo.toml:

pyo3 = { version = "0.23", features = [
    "eyre",
    "abi3-py37",
    "multiple-pymethods",
] }

with:

pyo3 = { version = "0.23", features = [
    "eyre",
    "abi3-py37",
    "multiple-pymethods",
    "experimental-inspect"
] }

Hey, I was just working on this issue. Could you clarify how I can check if the issue is resolved after making the changes? That would be really helpful in troubleshooting.

So, basically, if this functionality work, you should be able to see type information as well as documentation within python inspection: https://stackoverflow.com/questions/37288135/inspect-module-for-python that is not based on our current __init__.pyi . You can delete the __init__.pyi reinstall using maturin develop to see if you see any difference.

I believe it's still not working. I made the necessary changes and followed the steps you provided, but I’m still encountering an error when inspecting it.
