Bio feature added

[andoriyaprashant]

Description

The bio feature is implemented as a text field within the user's profile. When the ProfileScreen is loaded, the user's bio is retrieved from the database or storage and displayed in a "buildDetails" widget.

The bio feature in a classroom application is essential for users to introduce themselves, personalize the learning experience, foster a sense of identity and belonging, and create a supportive classroom community. It enhances connections, promotes engagement, and contributes to a more effective educational experience overall.
