Add arrow key mappings for tree-sitter parent/child/sibling nav (#1724)

Browse Source 
* Add arrow key mappings for tree-sitter parent/child/sibling nav

programmable mechanical keyboard, and use a layer switching key (think
fn) to send left down up right from the traditional hjkl positions.

* Add new bindings to docs
