[BUG] prospector fails when pyproject.toml contain multiple constraints dependencies

[ikappaki]

Describe the bug A clear and concise description of what the bug is.

When a multiple constraints dependency is specified in the pyproject.toml file, prospector fails with the following error:

 File "C:\venv311\Lib\site-packages\requirements_detector\poetry_semver\__init__.py", line 23, in parse_constraint
    or_constraints = re.split(r"\s*\|\|?\s*", constraints.strip())
                                              ^^^^^^^^^^^^^^^^^
AttributeError: 'list' object has no attribute 'strip'

To Reproduce Steps to reproduce the behavior:

1. pip install poetry and create a project

$ poetry new issue
Created package issue in issue

3. cd issue and update the myproject.toml to include an example package (in our case requests) with multiple constraints

#...
[tool.poetry.dependencies]
requests = [
    {version = "<=1.9", python = ">=3.6,<3.8"},
    {version = "^2.0", python = ">=3.8"}
]
#...

4. prospector -X .
5. The above error is raised

Expected behavior A clear and concise description of what you expected to happen.

The prospector should finish without errors

Environment (please complete the following information):

• OS: MS-windows
• Tool: prospector
• Prospector version 1.10.2
• Python version 3.11.4

Additional context Add any other context about the problem here. Putting the list of
dependencies installed, e.g. the output of pip freeze also helps.

The problem is that requirements-detector dependency assumes that a poetry dependency constraint is either a string or a map, but not a list.

(I've just realised that this is really a requirements-detector issue, but thought to still raise it here for perspective, feel free to migrate it to that project).

Thanks
