Change password screen should not have both "x" and "cancel"

[huayunh]

Describe the bug

These two buttons from the change password screen perform the same action — take a user to the previous screen

What is the expected behavior?

The page on docit says that there should be only one button, https://brightlayer-ui.github.io/patterns/user-auth#forgot--change-password

The bottom "cancel" button should be removed.

Note that on the web desktop version in React / Angular, there is a cancel button on the bottom, but there were no "x" on the top.

"Update" button should be full width of container
