st: Fix closure annotations

Quoting Ebassi https://www.bassi.io/articles/2023/02/20/bindable-api-2023/:

    Whenever you’re describing a function that takes a callback, you
    should always annotate the callback argument with the argument that
    contains the user data using the (closure argument) annotation

    You should not annotate the data argument with a unary (closure).

    The unary (closure) is meant to be used when annotating the callback
    type

Recently gobject-introspection became a bit more strict with this and
that generated some warnings:

    Warning: St: invalid "closure" annotation: only valid on callback
    parameters

This commit fix all the closure annotations.
