Removing wheel and setuptools as Dependencies for pip

Starting with Python 3.13, pip will no longer have setuptools and wheel as dependencies by default. While this default made sense at the time conda-forge was started (over 8 years ago!), with the advent of Python packaging build backends (e.g., flit, poetry, hatchling, etc.), this default is no longer correct. Instead, you will need to specify wheel and/or setuptools explicitly in the host section of your recipe if you need them. At first, pip for versions of Python before 3.13 will be unaffected. However, after the completion of the Python 3.13 migration, we will remove these dependencies from pip for all versions of Python. Follow GitHub issue #2252 for more information and updates.
