conda-forge:: removed from environment.yaml

[schuylermartin45]

pytest-socket is now widely available on both conda-forge and defaults, allowing us to make this change.

The package on defaults appears to work. I added this:

    import requests
    requests.get("https://google.com")

to one of our test cases locally. The test failed with the socket exception, as anticipated.

NOTE: The integration testing failures are a known issue.
