Improve bindings to better match VS-Code (#8584)

Release Notes:

- Changed default keybindings in the VS Code keymap so that
`alt-[up|down]` now move lines up/down and`alt-shift-[up|down]`
duplicate lines up/down. Previous bindings for selecting larger/smaller
syntax nodes are now bound to `ctrl-shift-[left|right]`.
