Hello, I made a small change to fix the issue where some packages might not have the same name when import, which caused them to be incorrectly reported as missing instead of transitive, as described in in #827.

To ensure the correct package name is retrieved in module.py, I added an additional approach to check if the package is in the development environment:

`

def _get_package_name_from_metadata(self) -> str | None:
    """
    Most packages simply have a field called "Name" in their metadata. This method extracts that field.
    """
    try:
        name: str = metadata(self.name)["Name"]
    except PackageNotFoundError:
        name = self.is_package_installed(self.name)
        if name:
            return name
        return None
    else:
        return name

def is_package_installed(self, package_name: str):
    if importlib.util.find_spec(package_name):
        return package_name
    return None

`
This ensures that the package name can always be retrieved if it is in the environment, regardless of whether the package name and import name match. I also updated the test in test_module so that the package name for bs4 can now be detected.

I'm not sure if this adheres to your program framework or design logic, but I hope it helps. Thanks!
