[BUG] KeyError: 'version' when running in a folder with pyproject.toml which contains a path dependency

[char0lene]

Describe the bug
When you start prospector in a folder with a pyproject.toml (from poetry). And this file does contain a path path dependency; Then prospector throws a KeyError and does not execute, because apparently it misses a dependency version. (You can not include a version in the path dependency, as far as I observed.)

To Reproduce

1. have 2 poetries (in different directories)
2. include a path dependency in one poetry (A) to the other poetry (B)
3. open a terminal in the folder with poetry A
4. run prospector

Expected behavior

Traceback (most recent call last):

   sys.exit(main())

KeyError: 'version'

Environment (please complete the following information):

• OS: Kubuntu 22.04.
• Tool: prospector and poetry
• Prospector version: 1.8.4
• Python version: 3.10.6

Additional context

You need two pyproject.toml poetry files.

This looks like the same issue as #556 - there's a workaround in that issue if you need one. The fix for this in requirements_detector has been merged now, so hopefully a fixed version of prospector is not too far away 🤞

#556 is closed as fixed in 1.10 can this one also be closed?
