MNT: Use noarch python {{ python_min }} variable

[matthewfeickert]

Resolves #42

• Use 'python {{ python_min }}' syntax for the python requirements for noarch python recipes.
  • c.f. https://conda-forge.org/docs/maintainer/knowledge_base/#noarch-python
• Use a Jinja2 set statement for python_min to keep all the build metadata contained in the recipe/meta.yaml and override the global python_min with coffea's python_min of 3.9.
  • coffea v2024.10.0 reports a minimum Python of 3.8, but the dependencies on conda-forge are unable to install without Python 3.9+.
• Remove --no-deps --no-build-isolation 'pip install' options in recipes as the build tool (e.g. conda-build, rattler-build) will enforce all required 'pip install' options itself at build time.
  • c.f. Question: why is --no-deps --no-build-isolation set? conda/grayskull#582
• Add missing dependencies of fsspec-xrootd, requests, aiohttp.
• Add 'pip check' to tests.
• Add conda-forge/scikit-hep as feedstock maintainers.
• Use 'pypi.org'.
• Bump build number.

Checklist

• Used a personal fork of the feedstock to propose changes
• Bumped the build number (if the version is unchanged)
• [N/A] Reset the build number to 0 (if the version changed)
• Re-rendered with the latest conda-smithy (Use the phrase @conda-forge-admin, please rerender in a comment in this PR for automated rerendering)
• Ensured the license file is being packaged.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

This will now ensure that there are versions that work with the lower bound of the requires-python defined in the PyPI package. If the PyPI requires-python changes this workflow will fail (which is good) and it will then require bumping this.

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you, but it looks like there was nothing to do.

The dependencies fail to install on Python 3.8, so need to bump to Python 3.9+.

@conda-forge/coffea, this is ready for review. Let me know if you have any questions.
