Problem:
- `:InspectTree` was showing node ranges in 1-based indexing, i.e., in
vim cursor position (lnum, col). However, treesitter API adopts
0-based indexing to represent ranges (Range4). This can often be
confusing for developers and plugin authors when debugging code
written with treesiter APIs.
Solution:
- Change to 0-based indexing from 1-based indexing to show node ranges
in `:InspectTree`.
- Note: To make things not complicated, we do not provide an option or
keymap to configure which indexing mode to use.
