refactor: class to edit message_context

[xygyo77]

Description

AssignContextReader is a class that inherits from ArchitectureReader, but it implements almost none of ArchitectureReader's functions, making the code difficult to understand.
Delete the AssignContextReader class and change the implementation to be more in line with the actual situation.

Could you create a test for the ContextUpdater class?

@xygyo77 Could you create a test for the ContextUpdater class?

Since it is an alternative to the AssignContextReader class, I assume it is covered in caret_analyze/src/test/architecture/test_architecture.py.

• test_update_message_context()
• test_remove_variable_passing()

The above test case was able to test for this change. It seems that we don't need to add any additional tests. Thanks.
