Outline numbering references have changed

[bruce-usab]

I found a typo introduced by changing outline numbering format (from 1.1 to 1.2).

Excerpt from 1.2 Editor's Draft, 4.3 Text Equivalent Computation excerpt (emphasis added):

...This is accomplished via steps 2B and 2F, which are recursive, using the full set of rules to retrieve text from its own children or nodes it references.

I was quite confused until I looked up 1.1 and its 4.3 Accessible Name and Description Computation which does include a 2B and 2F.

I believe 2B should be 2.2 and 2F should be 2.6.

Thanks for catching this. It was overlooked during w3c/aria#2498 cc @MelSumner.
