[Patternfly] Accessibility of PatternFly Icons

[Jonathan Yu]

Hey experts,

In many of our examples [0], we use PatternFly icons with the simple form:

<span class="pficon pficon-close"></span>

Reading the Bootstrap documentation[1] today, I noticed that it suggests
using aria-hidden="true" to prevent screen readers from trying to speak out
the Unicode.  Should we update our examples to do the same?  Or do the
PatternFly icons achieve accessibility in some other way?

Cheers,

Jonathan
