Add the bio feature

At the home fragment in the main activity of the app, below the name of the user, we can see its email address. So instead of email address we need the bio of the user to be displayed there.

1. Go to 'app/src/main/res'
2. Click on 'Register activity'
3. Scroll down to 'add email field'
4. See error

Expected behavior
Bio should be displayed in the place of email address of the user.
