MNT: Use noarch python {{ python_min }} variable (#1)

* 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 hepdata-validator's python_min of 3.6.
* Add setuptools as build system as a 'host' requirement.
* Use 'pypi.org'.
* 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.
* Bump build number.
* MNT: Re-rendered with conda-build 24.9.0, conda-smithy 3.44.6, and conda-forge-pinning 2024.11.17.06.32.00
