Clean up recipe per recommendation

noarch: python recipes should usually follow the syntax in our [documentation](https://urldefense.com/v3/__https://conda-forge.org/docs/maintainer/knowledge_base/*noarch-python__;Iw!!A3Ni8CS0y2Y!7PZ8k4ULt2wE-SNI7FY8PJ9DPZHbq2twmrwC1Llj6N6b4wvE2JPyjxzUIlczcMF2K9mtXLwCGPlbD5apkvg3BfAOv-zeRZg$) for specifying the Python version.

* [ ] For the host section of recipe, you should usually use python {{ python_min }} for the python entry.*
* [ ] For the run section of recipe, you should usually use python >={{ python_min }} for the python entry.
* [ ] For the test.requires section of recipe, you should usually use python {{ python_min }} for the python entry.

If the package requires a newer Python version than the currently supported minimum version on conda-forge, you can override the python_min variable by adding a Jinja2 set statement at the top of your recipe (or using an equivalent context variable for v1 recipes).
