Bug: Can keep typing in the bio field of user settings after 255 characters

[nickytonline]

We currently display a message saying the bio is too long in the user settings, but we're not leveraging the native maxLength HTML attribute to prevent someone from typing past the limit.

As well, since maxLength prevents you from typing or pasting text past 255 characters, the bio too long message will actually never appear so it can be removed from the component.

This is what happens when maxLength="255" is set.
