[ttml2] Fix CSS derivation of tts:displayAlign.

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

== Fix CSS derivation of tts:displayAlign. ==
CSS mapping should be `align-items`, not `justify-content`. The `tts:displayAlign` property is doing alignment in the BPD dimension, not IPD.
