Fix static annotation of pi.generate_multi_columns_probe

[MGAMZ]

pi.generate_multi_columns_probe can receive list[int] as num_contact_per_column. And by default, an int value will be automatically converted to list[int].

if isinstance(num_contact_per_column, int):
    num_contact_per_column = [num_contact_per_column] * num_columns

So changing the static annotation of num_contact_per_column.

Pull request overview

This PR corrects the type annotation for the num_contact_per_column parameter in generate_multi_columns_probe to accurately reflect that it accepts both int and list[int] types. The function has always supported list input (with automatic conversion from int to list), and this change aligns the type hint with the actual implementation.

Key Changes:

• Updated type annotation from int to int | list[int] for the num_contact_per_column parameter
