Use new sctk api (espanso#1901)

* Use new sctk api.

This also fixes the issue with the unresponsive window under wayland.

The cause appears to have been associating a callback with the keyboard
created, since this issue is reproducible with the new API if a
keyboard_with_repeat is created and a repeat callback passed.

* update sctk version

* clippy: ignore many_single_char_names in

* make clippy happy
