Add keybindings for accepting hunks (#19749)

I went with Cmd-Shift-Y on macOS (Ctrl-Shift-Y on Linux) for "yes accept
this individual hunk" - both are currently unused.

I went with Cmd-Shift-A on macOS (Ctrl-Alt-A on Linux) for "accept all
hunks" - both are unused. (Ctrl-Shift-A on Linux was taken, as is
Ctrl-Alt-Y, so although the pairing of Ctrl-Shift-Y and Ctrl-Alt-A isn't
necessarily obvious, the letters seem intuitive - "yes" and "all" - and
those key combinations don't conflict with anything.)

Release Notes:

- Added keybindings for applying hunks in Proposed Changes
