Python: parse conda.env in addition to requirements.txt

Right now Depandabot can only deal with requirement.txt files from PyPy but a lot of our repositories use Anaconda yaml files because of the performance increase with the Tensorflow installation. Thus, adding Conda yaml support would be essential for us!

The issue names requirements.txt and Anaconda/Conda YAML files as the dependency manifests to support. Start by locating the existing Python/PyPy requirements.txt handling, then determine how Conda YAML dependencies should be recognized and updated; done means Dependabot can process those repositories in addition to requirements.txt-only projects.
