[BUG] Failed to parse tool.poetry.dependencies with multiple constraints dependencies

[t20100]

Describe the bug

grayskull fails to parse poetry's multiple constraints dependencies syntax when run on the xypattern package with a grayskull.strategy.py_toml.InvalidPoetryDependency exception (see below).

This is the xypatterns's pyproject.toml [tool.poetry.dependencies] section.

To Reproduce

• Run grayskull pypi xypattern

Expected behavior

Have grayskull supporting poetry's multiple constraints dependencies syntax.

Outputs

Raised exception

Additional context

As a quick workaround, I added

@get_constrained_dep.register
def __get_constrained_dep_list(dep_spec: list, dep_name: str):
    conda_version = encode_poetry_version(dep_spec[0].get("version", ""))
    return f"{dep_name} {conda_version}".strip()
