Git commit modal command (#26405)

Fix KeyBinding::for_action() to use the active focus handle instead of
what was
rendered last.

This makes the UI consistently chose the cmd-escape binding for close
(because escape in the editor is editor::Cancel?),
so force it to be "escape"

Release Notes:

- git: Fixed escape tooltip in commit modal
