textproc/py-pygments: Clean up BUILD_DEPENDS

from pyproject.toml:
[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"

from CHANGES:
- Use Hatchling as a build backend instead of setuptools.
  This change is transparent to most users. Distribution packagers
  who build without build isolation need to add hatchling as a build
  dependency and remove setuptools. People downloading source distributions
  and wheels from PyPI directly should note that they now have ``pygments``
  in their file names instead of ``Pygments``. (#2573)
