feat(treesitter): clarify similar 'get_node_range' functions

The private 'get_node_range' function from the languagetree module has
been renamed and remains private as it serve a purpose that is only
relevant inside the languagetree module.

The 'get_node_range' upstreamed from nvim-treesitter in the treesitter
module has been made public as it is in itself a utlity function.
