[ttml2] br is omitted from timeContainer list

nigelmegitt has just created a new issue for 
https://github.com/w3c/ttml2:

== br is omitted from timeContainer list ==
In **§12.2.4 timeContainer** the list of elements for which 
`timeContainer` applies omits `br`, yet in **§8.1.7 br** it is clear 
that `br` should be in the list.
