Added user-select-text class

[gsartori]

Description

Added missing user-select-text class to implement the text selection behaviour as documented: https://developer.mozilla.org/en-US/docs/Web/CSS/user-select

Motivation & Context

Bootstrap does not implement the text selection as a class. When we set user-select-none to a container element, we cannot use user-select-auto to be able to select on a children element, we need user-select: text.
