FIX: Set python_min of Python 3.8

[matthewfeickert]

• Resolves Incorrect minimum Python version #47
• Required to fix MNT: Use noarch python {{ python_min }} variable pyhf-feedstock#28 (comment)

Description

• 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
• Add recipe/conda_build_config.yaml to override the global python_min with hatchling's python_min of 3.8.
• Install with recommended --no-deps --no-build-isolation options to ensure build dependencies are correct.
• Update to 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.
I do have some suggestions for making it better though...

For recipe/meta.yaml:

• No valid build backend found for Python recipe for package hatchling using pip. Python recipes using pip need to explicitly specify a build backend in the host section. If your recipe has built with only pip in the host section in the past, you likely should add setuptools to the host section of your recipe.

I assume that build backends are immune from this. I'm not sure if there is some way to indicate to conda-forge that they are self sufficient.

@conda-forge/hatchling this is ready for review.

Good catch, thank you!
