Remove decrypt arg-docs mismatch (#86128)

* Remove decrypt arg-docs mismatch

Removes the use of the arg in the action plugin
and removes the associated doc fragment. Changes
no behavior because the lack of decrypt in the
argspec prevents a value being passed in and
the args.get('decrypt', True) means that it is
always true.
