Use typography.textAlign for the pullquote's default alignment - #124

Description

Moves the pullquote's default left alignment from its custom css string to typography.textAlign in theme.json. Pullquotes look the same, but Styles › Blocks › Pullquote now shows left as the default, and picking another alignment there works. Before, the custom CSS overrode it.

Testing Instructions

1. Add a pullquote to a post. It's left aligned on the front end and in the editor.
2. Set another pullquote to center or right from the block toolbar. It follows that alignment.
3. Go to Styles › Blocks › Pullquote. Text alignment shows left selected.
4. Pick Center there. Pullquotes without their own alignment are now centered. On trunk, nothing changes.
5. Repeat with a color variation such as After Hours.
