Conda smithy makes an HTTP request without timeout. This can cause a hang/deadlock - in my case for longer than 1 minute. Nothing was happening, no CPU in htop, no logs.

When I hit ctrl+c the traceback showed the program got stuck in:

def get_most_recent_version(name, include_broken=False):
    request = requests.get(
        "https://api.anaconda.org/package/conda-forge/" + name
    )

which lacks a timeout.

This PR adds a timeout of 60 seconds which should be reasonable and prevent deadlocks. As smithy runs in CI, it's probably a good idea to have it fail rather than stall indefinitely.

Ah, btw, please add a news/ file with a brief description of the changes and the PR number. Something like:
