Always include "Show Logs" button for window messages (#600)

## Summary

This PR includes a "Show Logs" button for all window messages from Ruff.
This might be useful to reduce the friction for the users in figuring
out where the logs are. This is something I saw when looking at
koxudaxi/ruff-pycharm-plugin#463 description.
