doc: fix type alignment for CREATE TABLE in triggers
Datatypes in CREATE TABLE statements in the examples were vertically
aligned in most cases, a few examples were unaligned with a single
space. This makes sure all examples on the same page are consistently
aligned.
Patch by Laurenz Albe with some additional fixups by me.
