bg-* and text-* classes aren't controlled by @brand-* color variables

[vipseixas]

Only text-primary and bg-primary classes are affected by changes at the color section of the Customizer.

Those colors are currently controlled by the @state-*-* variables instead of the @brand-* variables.

Sorry for the false bug report, but this is a little inconsistent since when you change the @brand-primary it changes the .text-primary and .bg-primary.
Maybe you should only change the text "Define colors for form feedback states and, by default, alerts." for "Define colors for form feedback states, contextual colors and, by default, alerts." just to clarify.

Oh yes, I quite agree it's inconsistent and could use justification; was just noting the actual cause since it wasn't truly customizer-related.

We'll aim to do better on this for v4. For now, it stays as a won't fix. Thanks though!
