Cannot detect imported path does not exist

[redcray]

xx.aa is a non-existent path, ruff indeed cannot resolve to this path, but did not give any hint.
I don't know the specific rules of grammar detection, but I think this is a feature that can be supported?

Thanks!

• A minimal code snippet that reproduces the bug.

from xx.aa import Config
Config()

• The command you invoked (e.g., ruff /path/to/file.py --fix), ideally including the --isolated flag.

ruff check .

• The current Ruff settings (any relevant sections from your pyproject.toml).
  none

• The current Ruff version (ruff --version).
  ruff 0.0.282

We wrote a Python module resolver that can support this in theory, but the details are hard to get right, since we might need to know about your virtualenv to know if the module is third-party.

On second thought, we could just detect whether this package (xx) is first-party, and then see if the module exists within the first-party package, and raise if not.
