Missing imports sections don't always show the parent module.

It's possible to get typing_copilot to generate mypy.ini files including lines like this:

[mypy-schematics.types.*]
ignore_missing_imports = True

This can make for overly verbose mypy.ini files, if multiple submodule paths like this are individually suppressed. Since it's very likely in that case that the entire schematics package is missing type hints, we should simplify that to the following:

[mypy-schematics.*]
ignore_missing_imports = True
