docs-bug(Button): Mention that the MDC buttons have a more specific selector for the button color

Documentation Feedback

The MDC buttons have a more specific selector for the button color (there was a related issue angular/material.angular.io#1164 in this project earlier).

However, at the moment the Guide Migrating to MDC-based Angular Material Components misses this moment.

I propose to add mentioning of the above change into the guide.

Currently the only supported way of changing a button's color is through theming. Later this year we will support further customization of color with a new token-based theming API.
