The property never returns None. This simplifies user code containing
types that already knows a bin directory must exist. It avoids the need
to pepper calling code with:
assert session.bin is not None
Or
# type: ignore
For example, in pip:
https://github.com/pypa/pip/blob/062f0e54d99f58e53be36be5a45adad89e2429fb/tools/automation/release/__init__.py#L29
A noxfile that tries to access a bin directory that doesn't exist will
now raise an exception.
