bug#61231: 30.0.50; treesit-induce-sparse-tree: rename LIMIT to DEPTH

[Mickey Petersen]

Minor thing, really, but I think we should rename LIMIT to DEPTH.

LIMIT has a rather specific meaning to me when it comes to graph
theory. It implies a stop search after a certain number is reached.

Here, it really means *depth*; that is, the tree will cease to scan
once it has reached a certain depth in the node tree, as opposed to
having reached its limit on matches.
