python: fully support 3.14
In https://github.com/posit-dev/positron/pull/9613 we added preview support for Python 3.14. This is because it's still in prerelease, so a handful of test dependencies haven't published wheels for it yet, and our CI isn't set up to build them from source, so we skipped tests for them on 3.14:
- fastapi
- geopandas
- haystack
- ibis
- lightning
- pyarrow
- torch
- snowflake
(I think many of these are waiting on pyarrow; see their issue at https://github.com/apache/arrow/issues/47438).
Once these test dependencies are ready, we should enable the tests by dropping the python_version < '3.14' in various requirements.txt files and ensuring they're all run successfully.
Once the tests are passing, we can first-class Python 3.14 in the New Project Flow by reordering the list in extensions/positron-python/src/client/pythonEnvironments/creation/provider/uvUtils.ts, dropping the (preview) language in the same file, and dropping the (preview) language in src/vs/workbench/browser/positronNewFolderFlow/utilities/uvUtils.ts.
Also we can run the Python Tests CI job on ['3.9', '3.14'] instead of ['3.9', '3.13', '3.14'].
We will probably need to bump our pydantic version, due to this error: https://github.com/python/cpython/issues/130881
During verification, we may want to consider moving the Python version here to 3.14: https://github.com/posit-dev/positron/blob/main/.github/actions/install-python/action.yml
Is there anywhere else in the main (non-Python-extension) CI where we want to bump to 3.14?

3.14 seems to be working well for me locally.
Will look into updating CI to 3.14 with https://github.com/posit-dev/positron/issues/10949
