Adding dependency "nautobot[napalm]" breaks Invoke's image URL generation

[rlad78]

I was trying to enable Napalm functionality on our Nautobot instance, using the instructions from Nautobot Documentation -> User Guide -> Administration -> Installation -> Installing Nautobot. In the context of the new poetry + Invoke setup, that just means doing the following:

poetry add nautobot[napalm]@2.1.1

That results in the following being changed in pyproject.toml:

- nautobot = "2.1.1"
+ nautobot = {version = "2.1.1", extras = ["napalm"]}

When running any Invoke command, the following lines get run: https://github.com/nautobot/nautobot-docker-compose/blob/40eec0879a0e8f271eedcaf0f67ade55166ca6b5/tasks.py#L44-L47

Which evaluates like so:

>>> parsed_toml["tool"]["poetry"]["dependencies"]["nautobot"]
{'version': '2.1.1', 'extras': ['napalm']}

...when, instead, the logic is intended to parse just the version string for the Nautobot dependency.

Later, when trying to synthesize the URL for the required Docker image, the following exception happens:
