@rbxts/types: unrelated but 1.0.463

Description

RojoResolver gets stuck on anything that recurses, for example a node with "$path": ".", because it keeps walking that directory and rediscovering the node, then walking the directory and so on...

Minimal Reproduction

{
	"name": "something",
	"tree": { "$path": "." }
}

Expected behavior:

Compiler detects that the node has already been walked, and either continues or emits an error

Current behavior:

Compiler loops forever or exceeds call stack limit
