A small modification in the pop-up message for wrongly entered credentials

I'm currently following the tutorial at 5. Installation – Mastering Plone 6 development — Plone Training 2024 documentation. During my progress, I observed that when an incorrect password or username is entered, the displayed pop-up message remains unchanged. I believe it would enhance user experience if the message specifically indicated 'Invalid username or password' in red text, providing clearer feedback. I kindly request your guidance and support to implement this improvement.
In the instance.yaml file I have modified the username & password, to observe this behaviour.
