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

* Add arrow key mappings for tree-sitter parent/child/sibling nav This helps my use case, where I use a non-qwerty layout with a 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
