fix(computer-use): probe Linux editables via get_editable_text_iface (#10586)

set_value looked up node.is_editable_text before attempt() ran. GI bindings
from at-spi2-core < 2.53 (e.g. Ubuntu 24.04) do not expose that function, so
the AttributeError escaped and every set-value failed. Probe with
get_editable_text_iface, which has been bound since 2.9.2 and checks the same
interface.

Closes #10569
