Show error message for invalid password during user registration

Hey Plant-it community!

What's new?

This PR fixes #280, i.e. addresses the issue where no error message was displayed when a new user attempted to register with an invalid password, particularly one that did not meet the 6-character minimum length requirement.

Error Messaging: Now, when a user tries to register with a password that does not meet the minimum length requirement, an appropriate error message will be shown on the frontend.

Why is it important?

This update enhances the user experience by providing immediate feedback when an invalid password is entered, preventing confusion.

How to Use?

No special instructions are required. Users will now see an error message if they attempt to register with an invalid password.

Cheers and happy planting! 🌿🌼
