XAccessibleSelection: Don't reference non-existing methods in doc

There are no 'XAccessibleSelection::deselectSelectedChild'
and 'XAccessibleSelection::getSelectedChild' methods, so don't
mention them in the documentation for
'getSelectedAccessibleChildCount'.

First, there's 'XAccessibleSelection::getSelectedAccessibleChild',
but not 'XAccessibleSelection::getSelectedChild', so update that
accordingly.

Second, there's no 'XAccessibleSelection::deselectSelectedChild',
and 'XAccessibleSelection::deselectAccessibleChild' doesn't take an
index into the selection, but a child index, s. its documentation
and the commit message of pending Gerrit change
Change-Id: I3c63c647e61baaa6288ffd545d8d89d8b94231de
("gtk3 a11y: Use correct index when deselecting child")
on how the semantics of AT-SPI functions with corresponding
names differ.

sounds like there might temporarily have existed a draft implementation
that actually took an index into the selection rather than
a child index.)
