Ensure ACF field block output supports different settings of the align attribute

[bobbingwide]

Several ACF field types would benefit from being able to select the Alignment; attribute align.
This doesn't appear to work for "align": "center"

Setting	OK?
none	OK
left	OK
right	OK
center	No

It appears that for aligncenter to work the block needs the class has-text-align-center.
See oik_server_side_wrapper() for example code, passing $extra_attributes to get_block_wrapper_attributes()
