Fix deprecated calls to atk in atk-adaptor
The build log has a bunch of these:
./atk-adaptor/adaptors/value-adaptor.c: In function ‘impl_set_CurrentValue’:
../atk-adaptor/adaptors/value-adaptor.c:183:3: warning: ‘atk_value_get_current_value’ is deprecated: Use 'atk_value_get_value_and_text' instead [-Wdeprecated-declarations]
183 | atk_value_get_current_value (value, &dest);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
../atk/atkvalue.h:126:11: note: declared here
126 | void atk_value_get_current_value (AtkValue *obj,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
We can finally fix them, since atk and atk-adaptor are released in lockstep.
