build(aio): ensure the correct decorator properties are merged (#24289)

Previously only the `description` and `usageNotes` were being copied over
from the call-member of the decorator interface. Important properties such
as `shortDescription` were missed.

These are now added and the code has been refactored to make it simpler and
clearer to update which properties get copied as the requirements change.
